Synthesis of glycogen particle is done by Tyr 1 9 4 of glycogenin which reacts with glucose unit and produce tyrosyl glucose. UDP-glucose produces glucose unit. This complete reaction is catalyzing by the glycogenin. Working mechanism of this reaction is to be explained. Concept introduction: Complete mechanism is described by nucleophilic attack of aspartate which is residue of catalyst glycogenin.

Breakdown rxn of GIUCOSE. What is the Cleland diagram for the reaction glyceraldehyde 3-phosphate to 1,3 diphosphoglycerate? Based this on the following steps: a. Glyceraldehyde3-phosphate binds to the enzyme,E b. NAD binds to the enzyme E then is reduced to NADH c. NADH leaves the enzyme d. Phosphate binds to the enzyme and attacks the glycerate phosphate attached to the enzyme e. 1,3-disphosphoglycerate leaves the enzyme as the final procut

The Payoff Phase of Glycolysis in Skeletal Muscle In the skeletal muscle, in anaerobic conditions, glyceraldehyde 3- phosphate is converted into pyruvate during the payoff phase of glycolysis; and this pyruvate is reduced into lactate during lactic fermentation. 1-Write the 11 balanced biochemical equations corresponding to all| the reaction steps leading to the conversion of glyceraldehyde-3- phosphate into lactate through glycolysis followed by lactic fermentation. 2-Write the net equation of the whole transformation process (i.e. with glyceraldehyde-3-phosphate as the starting substrate; and lactate as the end product).
