What are the functions of the cell membrane?

Where are proteins found in the cell membrane?
Answer: The plasma membrane is a dynamic structure. It is composed of 2 layers of lipid material with protein molecules located through out. The phospholipids move at a rate of 2um. /sec. while the proteins move at a much slower rate. The phospholipids have 2 definite ends, a hydrophilic (focusing to the outside and inside of the membrane) and a hydrophobic one (forming the center of the membrane). The proteins are of two types Integral (passing through the width of the membrane act as transport channels) and peripheral (act as recognition sites). These peripheral proteins contain carbohydrates to help in cell to cell recognition. These carbohydrates are called oligosaccharides. If they bind to proteins they become glycoproteins, if they bind to lipids, they become glycolipids. Cholesterol molecules are found in animal membranes to help add support to its structure. The majority of the phospholipids contain unsaturated fatty acids to keep it fluid.

Which material matches the function of the following cell organelles?

I have to make a project which is due tommorow! Please help me! I need to know the materials found in our everyday world to match the following organelles and their functions: -Cell Membrane -Chromosomes -Nucleolus -Nuclear Envelope -Vacuole -Ribosomes -Golgi Apparatus -Lysosomes -Mitochondria -Rough ER -Smooth ER
Answer: If your talking more relating them to the roles they would represent..... Then: Mitochondria-power house (produces energy) Cell membrane- doors or guard (lets things in and out) Golgi-postal service (package and transport) Vacuole-water fountain or water bottle (water source) Rough ER- like train on tracks or semis on highway (transport proteins) Lysosome-either garbage men or army(clean up and destroy) Ribosome-factory (assembly line for amino acids being put together into proteins) Smooth ER-can also be highway but no semis Nucleolus- either builder of factory or manager of assembly line (make ribosomes) Nuclear envelope-guards to city center (controls what gets in and out of nucleus [control center]) Chromosomes-blueprints for the city Hope this is what you need and its not too late

I have a 30 min essay to write on this topic. Now - 30 mins seems like nothing! Im torn between wanting to include major details and not knowing what to throw out of the essay to be able to cram in what is required. What do you think a 30 min 1-1.5 side of paper essay would include? Many thanks
Answer: The cell membrane (also called the plasma membrane, plasmalemma or "phospholipid bilayer") is a semipermeable lipid bilayer found in all cells.[1] It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes, and also serves as the attachment point for both the intracellular cytoskeleton and, if present, the cell wall. Function The cell membrane surrounds the cytoplasm of a cell and, in animal cells, physically separates the intracellular components from the extracellular environment, thereby serving a function similar to that of skin. In fungi, bacteria, and plants an additional cell wall forms the outermost boundary, however, the cell wall plays mostly a mechanical support role rather than a role as a selective boundary. The cell membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix to help group cells together in the formation of tissues. The barrier is selectively permeable and able to regulate what enters and exits the cell, thus facilitating the transport of materials needed for survival. The movement of substances across the membrane can be either passive, occurring without the input of cellular energy, or active, requiring the cell to expend energy in moving it. The membrane also maintains the cell potential. Specific proteins embedded in the cell membrane can act as molecular signals which allow cells to communicate with each other. Protein receptors are found ubiquitously and function to receive signals from both the environment and other cells. These signals are transduced into a form which the cell can use to directly effect a response. Other proteins on the surface of the cell membrane serve as "markers" which identify a cell to other cells. The interaction of these markers with their respective receptors forms the basis of cell-cell interaction in the immune system. Structure Lipid bilayer Diagram of the arrangement of amphipathic lipid molecules to form a lipid bilayer. The yellow polar head groups separate the grey hydrophobic tails from the aqueous cytosolic and extracellular environments.The cell membrane consists of a thin layer of amphipathic lipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer containing the cellular components approximately 7 nm thick, barely discernible with a transmission electron microscope.[1] The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevents hydrophilic solutes from passively diffusing across the band of hydrophobic tail groups, allowing the cell to control the movement of these substances via transmembrane protein complexes such as pores and gates. Flippases and Scramblases concentrate phosphatidyl serine, which carries a negative charge, on the inner membrane. Along with NANA, this creates an extra barrier to charged Moities moving through the membrane. Integral membrane proteins The cell membrane contains many integral membrane proteins which pepper the entire surface. These structures, which can be visualized by electron microscopy or fluorescence microscopy, can be found on the inside of the membrane, the outside, or through-and-through. They include synapses, desmosomes, clathrin-coated pits, caveolaes, and different structures involved in cell adhesion. Membrane skeleton The cytoskeleton is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to, as well as forming organelles which extend from the cell. Anchoring proteins restricts them to a particular cell surface — for example, the apical surface of epithelial cells that line the vertebrate gut — and limits how far they may diffuse within the bilayer. The cytoskeleton is able to form appendage-like organelles, such as cilia, which are covered by the cell membrane and project from the surface of the cell. The apical surfaces of the aforementioned epithelial cells are dense with finger-like projections, called microvilli, which increase cell surface area and thereby increase the absorption rate of nutrients. The cell membrane acts as a protecting body. Structure and the Fluid mosaic model According to the fluid mosaic model of S. Jonathan Singer and Garth Nicolson, the biological membranes can be considered as a two-dimensional liquid where all lipid and protein molecules diffuse more or less freely[2]. This picture may be valid in the space scale of 10 nm. However, the plasma membranes contain different structures or domains that can be classified as (a) protein-protein complexes; (b) lipid rafts, (c) pickets and fences formed by the actin-based cytoskeleton; and (d) large stable structures, such as synapses or desmosomes. The flud mosaic model can be seen when the membrane proteins of two cells (eg a human cell and a mouse cell) are tagged with different coloured fluorescent labels. When the two cells are fused, the two colours intermix, indicating that the proteins are free to move in the 2D plane.

cell membrane functions: true or false?

free ribisomes differ from membrane-bound ribosomes in that free ribosomes specialize in synthesizing proteins for export (secretion) from the cell. one function of integral proteins in the plasma membrane of cells is to form channels to allow passage of nonpolar solutes into the cell. thanks for your help!
Answer: true and true. From Wiki: Free ribosomes Free ribosomes are free to move about anywhere in the cytoplasm (within the cell membrane). Proteins that are formed from free ribosomes are used within the cell. Proteins containing disulfide bonds using cysteine amino acids cannot be produced outside of the lumen of the endoplasmic reticulum. [edit] Membrane-bound ribosomes When certain proteins are synthesized by a ribosome they can become "membrane-bound". The newly produced polypeptide chains are inserted directly into the endoplasmic reticulum by the ribosome and are then transported to their destinations. Bound ribosomes usually produce proteins that are used within the cell membrane or are expelled from the cell via exocytosis. Free and membrane-bound ribosomes differ only in their spatial distribution; they are identical in structure and function. Whether the ribosome exists in a free or membrane-bound state depends on the presence of a ER-targeting signal sequence on the protein being synthesized. [

What are the functions of cell membranes?

describe AT LEAST 3 separate functions. Include a brief background on membrane structure to support your descriptions. Use the following vocabulary: phospholipid bi-layer; fluid mosaic model; active and passive transport; diffusion and osmosis. Thanks. this is college level stuff here, just tryin to get some useful information..
Answer: 1. cell membrane gives the cell its shape as you see it under the microscope.that is the fluid mosaic model. 2.the cell membrane defines waht goes in and what is going out. it lets in water and nutrients and lets out waste materials.active and passive transport plus diffusion and osmosis apply here. 3.the phospholipid layer is strong and protects the organelles from shocks and pathogens. you should note that the cell membrane of a plant and an animal have slightly different structures and therefore functions vary.

describing the functions of the cell membrane and the cell wall?

it would be of very help, its on an essay i need to write, and i cant seem to get a strong understanding of it..
Answer: cell wall and cell membrane serves as the shield of the cell in its outside environment in general.. I'll give you the outline of uses: Cell Wall -Found ONLY on plants, bacteria, fungi, algae, and archea -Provides Rigidity for plants -Maintaining the amount of water entering and leaving the cell (osmosis) -Filters materials entering the cell (semi-permeable) -Lies outside the cell membrane ~Cell Wall for plants -It's major component is cellulose -Compose of 3 layers ....= * The middle lamella, a layer rich in pectins. This outermost layer forming the interface between adjacent plant cells and glues them together. * The primary cell wall, generally a thin, flexible and extensible layer formed while the cell is growing. * The secondary cell wall, a thick layer formed inside the primary cell wall after the cell is fully grown. It is not found in all cell types. In some cells, such as found xylem, the secondary wall contains lignin, which strengthens and waterpoofs the wall. ~Cell Wall for algae -major component is cellulose ~Cell Wall for bacterias (including archea) -Made up of cellulose and chitin For the cell membrane -It is found on ALL cells -Semi Permeable -Control the fluids inside the cell (to prevent shrinkage or expansion) -Some proteins allow cell to communicate on each other (concrete example is when the cell becomes tissue-organ-organ system-human being)

How does the endoplasmic reticulum and cell membrane work together to preform the life functions of the cell?

AP Bio. ive looked evrywhere :(
Answer: Rough endoplasmic reticulum is used to manufacture proteins that will subsequently end being embedded in the cell membrane (or anchored to it) or be released outside of the cell. Meanwhile the smooth ER adds phospholipids to the cell membrane via exocytosis so they work together to maintain a normal cell size. Hope this helps!
