How do ribosomes, RER, Golgi Complex, and the cell membrane function together?


Answer: Ribosomes: functions in protein synthesis. They are not considered a membrane bound organelle. Ribosomes are built from 2 subunits. Its only when these subunits are properly placed together that the ribosome becomes functional. The large subunit is composed of 45 proteins and 3 molecules of RNA while the small subunit consists of 33 proteins molecules and 1 RNA. Fully assembled it measures 20-30 nm. Sometime ribosomes work in units called polysomes. There are 2 types of ribosomes: bound and free. The bound are found attached to the ER, while the free ones float around in the cytosol. The proteins made by the free will usually stay within the cell, while the bound are destined to become part of the membrane system or exported from the cell. Endoplasmic Reticulum: consists of a network of membranous tubules and sacs called cisternae. The ER is continuous with the nuclear membrane. There are 2 types of ER: smooth and rough. Smooth does not contain ribosomes where the rough form does. Rough ER: Antibody production occurs in the rough ER. Many secretory proteins are also produced here. These proteins are glycoproteins, proteins and carbohydrates combined. The carbohydrate is called an oligosaccharide. These secretory proteins are bound in special structures called transport vesicles. The Rough ER is involved with membrane production. Golgi Apparatus: a series of flattened membranous sacs, stacked like pita bread. The functions are : synthesis, storing, sorting and shipping of materials. The dictysomes have 2 distinct faces: the cis face receives the material and the trans face ships materials. The cis face is close to the ER. The trans face gives rise to vesicles full of material and pinch off. Exocytosis: Movement of materials out of the cell. These usually are trapped in vesicles that merge with the plasma membrane and release their contents. They are usually produced by the ER or Golgi Apparatus. Endocytosis: Movement of materials into the cell. This is subdivided based on the type and size of material being transports. 1. Phagocytosis: Plasma membrane surrounding a large solid piece of material or cell, forming a vacuole and digesting it in conjunction with lysosomes. 2. Pinocytosis: plasma membrane forming a vacuole surrounding liquids and taking them into the cell. 3. Receptor mediated: special receptors embedded in the membrane will pick up specific materials and bring them into the cell.

Some Facts about FAT that are worth knowing!

Fats are vital to your health. They transport oxygen to every cell in your body, and they are the basis for every hormone, brain, and nervous system function. Fats are the chemically active part of your cell membranes. ...

cell membrane?

what is the cell membranes function? i know that it protects the cell and gives it structure and that it also allows transportation into and out of the cell. Is there anything that I am missing? Also, what are the components of the cell membrane? Thanks!
Answer: Functions of cell membranes * Controlling what goes in and out of the cell. * Anchoring of the cytoskeleton to provide shape to the cell * Attaching to the extracellular matrix to help group cells together in the formation of tissues * Transportation of particles by way of ion pumps, ion channels, and carrier proteins * Containing receptors that allow chemical messages to pass between cells and systems * Participation in enzyme activity important in such things as metabolism and immunity The cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and steroids. The relative composition of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant. The fatty acid chains in phospholipids and glycolipids usually contain an even number of carbon atoms, typically between 14 and 24. The 16- and 18-carbon fatty acids are the most common. Fatty acids may be saturated or unsaturated, with the configuration of the double bonds nearly always cis. The length and the degree of unsaturation of fatty acids chains have a profound effect on membranes fluidity The cell membrane plays host to a large amount of protein which is responsible for its various activities.Three groups of membrane proteins can be identified:Integral proteins ,Lipid anchored proteins ,Peripheral proteins

How does the cell membrane function?

Okay, so I know that the cell membrane is made up of a phospholipid bi-layer but I dont really get how things pass through the membrane. The heads of the phospholipids are polar but doesnt that mean it dissolves in water??? Also, water is able to pass though the membrane....but wouldnt the fatty acid ends of the phospholipid repel it or something???

what characteristics are used to classify stars?what is the function of the cell membrane?

also what is the best description of the function of the mitochondria?why is a bacterial cell different from an animal cell?cells in many-celled organisms are often quite_________.also the term that refers to the movement of materials through a cell membrane when the cells energy is required is________. also the term that refers to the movement of materials through a cell without using the cells energy is________ . could you please help me because i cant find nothing in the computer please and i have a lot of more questions please help me we dont get this homework please!!!!!!!!!!!!!!!!!!!!
Answer: Stars are classified by their spectral type and absolute magnitude. The main spectral types run OBAFGKM, in order of decreasing temperature. The absolute magnitude is the brightness of the star corrected for distance. A plot of these two characteristics for a group of stars is called a Hertzsprung-Russel diagram. Can't help with the biology stuff, sorry.

What is the function of cholesterol molecules in cell membrane?

I saw in a book that the cholesterol molecules are embedded within the cell membrane in between the phospholipids. What do you think is the function of these cholesterol molecules.
Answer: Cholesterol molecules function as the basic skeleton of the cell membrane giving it the lipid bi-layer structure which is necessary for most of its functions. Cholesterol molecule forms the hydrophobic part of the cell membrane.
