What is the relation of glucogenolysis gluconeogenesis and glycogenesis in metabolism?
What is the relation of glucogenolysis gluconeogenesis and glycogenesis in metabolism?
Answer: is it glycogenolysis? if yes then its is the process in which glycogen is cleaved to smaller sub unit glucose in liver (glycogen is made up of thousands of glucose unit, thus a polymer)
Gluconeogenesis is the process in which body synthesize glucose from other sources.

What hormone controls glycogenesis? Why is insulin so important and what is the debranching enzyme called?
Answer: Hormones controlling glycogenesis:
============================
Adrenaline
Glycogen phosphorylase is activated by phosphorylation, whereas glycogen synthase is inhibited.
Glycogen phosphorylase is converted from its less active b form to an active a form by the enzyme phosphorylase kinase. This latter enzyme is itself activated by protein kinase A and deactivated by phosphoprotein phosphatase-1.
Protein kinase A itself is activated by the hormone adrenaline. Adrenaline binds to a receptor protein which activates adenylate cyclase. This in turn activates the secondary messenger system, by causing the formation of cyclic AMP, which acts allosterically to activate protein kinase A
Returning to glycogen phosphorylase, the less active form (b) can itself be activated without the conformational change. 5'AMP acts as an allosteric activator, whereas ATP is an inhibitor, as already seen with phosphofructokinase control this helps to change the rate of flux in response to energy demand.
Adrenaline not only activates glycogen phosphorylase, but also inhibits glycogen synthase. This amplifies the effect of activating glycogen phosphorylase. This inhibition is achievied by a similar mechanism, as protein kinase A acts to phosphorylate the enzyme and this lowers activity. This is known as co-ordinate reciprocal control.Refer to glycolysis for further information of the regulation of Glycogenesis
Insulin
Insulin has an antagonistic effect compared to adrenaline. The glycogen synthase enzyme can be kept in a low activation form by insulin, which switches off one of its kinase enzymes – glycogen synthase kinase 3
The two debranching enzymes are:
4-α-D-glucanotransferase (EC 2.4.1.25) - glucosyltransferase
amylo-α-1,6-glucosidase (EC 3.2.1.33) - glucosidase

Shouldnt GLUCONEOGENESIS take place in a insulin dependent (diabetes mellitus) person,NOT Glycogenesis?
It seems to make sense that instead of Glycogenesis, Gluconeogenesis should take place because glucose is from a non-carb source, that being insulin, which is basically protein...
Answer: Insulin is just a hormone, it is not involved in the metabolic processes that it stimulates. Hormones are usually metabolised and removed form the body as waste after they have spent a certain amount of time circulating in the body.
So, although insulin IS a protein, it is not broken down and used to form glycogen. Instead, it stimulates glucose uptake by some cells and then the glucose that is waken into the cells are used to form glycogen (glycogenesis).

I need to understand which metabolic pathways work under certain conc. conditions?
ie: Which pathway is active when glucose is high and atp is low in concentration? I missed the classes where she talked about this and I missed out. Now on these later tests we are still supposed to know this. I need to understand it, any book/website/whatever can help me understand this better is appreciated.
Pathways we have been studyin: Glycolysis, glycogenesis, glyconeogenesis, ect.
Answer: There are two pathways. Glycolysis-> (requires oxygen) pyruvate oxidation-> citric acid cycle->electron transport chain. The second if glycolysis-> (no oxygen) fermentation. The one that uses light produces 32 ATPs while the other only produces 2 ATP. This should help more "http://en.wikipedia.org/wiki/Glycolysis"

During glycogenesis, what does protein kinase do to a reaction? How many ATP molecules are used during ..?
How many ATP molecules are used during the first 5 reactions and where does glycolosis occur?
Answer: protein kinases are involved in a signal transduction cascade, where a series of proteins are phosphorylated to transduce/amplify a signal leading from a signal reception event. the first protein kinase is called PKA. the last kinase in the cascade effects a cytoplasmic/nuclear response.
2 ATP are used in the energy investment phase of glycolysis. glycolysis occurs in the cytoplasm, though some might argue that the later part of it occurs in the mito matrix (some books do not recognize the link reaction as a separate phase as glycolysis).

what is the difference between glycogenesis and glycogen metabolism?
Answer: Hmm....I could be wrong, but I believe that glycogenesis refers to the synthesis of glycogen from glucose molecules. This usually occurs when blood glucose levels are high. Glycogen metabolism is a more general term, and can refer to either the catabolism (breaking down) or anabolism (building up, or synthesis) of glycogen. I hope this helps

Answer: here is some info. on this:
Glycogenesis, Glycogenolysis,
and Gluconeogenesis
Biosynthesis of Glycogen:
The goal of glycolysis, glycogenolysis, and the citric acid cycle is to conserve energy as ATP from the catabolism of carbohydrates. If the cells have sufficient supplies of ATP, then these pathways and cycles are inhibited. Under these conditions of excess ATP, the liver will attempt to convert a variety of excess molecules into glucose and/or glycogen.
Glycogenesis:
Glycogenesis is the formation of glycogen from glucose. Glycogen is synthesized depending on the demand for glucose and ATP (energy). If both are present in relatively high amounts, then the excess of insulin promotes the glucose conversion into glycogen for storage in liver and muscle cells.
In the synthesis of glycogen, one ATP is required per glucose incorporated into the polymeric branched structure of glycogen. actually, glucose-6-phosphate is the cross-roads compound. Glucose-6-phosphate is synthesized directly from glucose or as the end product of gluconeogenesis.

Glycogenolysis:
In glycogenolysis, glycogen stored in the liver and muscles, is converted first to glucose-1- phosphate and then into glucose-6-phosphate. Two hormones which control glycogenolysis are a peptide, glucagon from the pancreas and epinephrine from the adrenal glands.
Glucagon is released from the pancreas in response to low blood glucose and epinephrine is released in response to a threat or stress. Both hormones act upon enzymes to stimulate glycogen phosphorylase to begin glycogenolysis and inhibit glycogen synthetase (to stop glycogenesis).
Glycogen is a highly branched polymeric structure containing glucose as the basic monomer. First individual glucose molecules are hydrolyzed from the chain, followed by the addition of a phosphate group at C-1. In the next step the phosphate is moved to the C-6 position to give glucose 6-phosphate, a cross road compound.
Glucose-6-phosphate is the first step of the glycolysis pathway if glycogen is the carbohydrate source and further energy is needed. If energy is not immediately needed, the glucose-6-phosphate is converted to glucose for distribution in the blood to various cells such as brain cells.

Biosynthesis of Glucose:
Gluconeogenesis:
Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. The starting point of gluconeogenesis is pyruvic acid, although oxaloacetic acid and dihydroxyacetone phosphate also provide entry points. Lactic acid, some amino acids from protein and glycerol from fat can be converted into glucose. Gluconeogenesis is similar but not the exact reverse of glycolysis, some of the steps are the identical in reverse direction and three of them are new ones. Without going into detail, the general gluconeogenesis sequence is given in the graphic on the left.
Notice that oxaloacetic acid is synthesized from pyruvic acid in the first step. Oxaloacetic acid is also the first compound to react with acetyl CoA in the citric acid cycle. The concentration of acetyl CoA and ATP determines the fate of oxaloacetic acid. If the concentration of acetyl CoA is low and concentration of ATP is high then gluconeogenesis proceeds. Also notice that ATP is required for a biosynthesis sequence of gluconeogenesis.
Gluconeogenesis occurs mainly in the liver with a small amount also occurring in the cortex of the kidney. Very little gluconeogenesis occurs in the brain, skeletal muscles, heart muscles or other body tissue. In fact, these organs have a high demand for glucose. Therefore, gluconeogenesis is constantly occurring in the liver to maintain the glucose level in the blood to meet these demands.
