Biochemistry help 1) Write the names of the degradative and the biosynthetic enzymes of glycogen metabolism that are targeted to regulate glycogen metabolism. 2) ) Discuss, by drawing structures, how hormones regulate the enzymes you name in Question 1. 3) Discuss, with structures, the reactions of the non-oxidative phase of the pentose phosphate pathway and show how the non-oxidative phase is used to synthesize all the pentoses in nature.
Reversible protein phosphorylation is a critical mediator of cellular physiology. What are the roles of phosphorylation...
Reversible protein phosphorylation is a critical mediator of cellular physiology. What are the roles of phosphorylation with respect to the Tau protein? How does the presence of multiple phosphorylation sites complicate our understanding it’s regulation (or does it?). In term of protein evolution, is this a selective advantage, side effect, or something else entirely?

a. The metabolism of glucose by glycolysis to acetyl-coenzyme A, followed by the TCA cycle, releases CO2 molecules by oxidative decarboxylation reactions. Write down the oxidative decarboxylation reactions that result in CO2 production. Name the enzyme involved in each reaction and give the names and complete structures of all reactants and products. Only abbreviated names of enzyme cofactors are required. (b) From the steps drawn in part (a) above, how many total ATP molecules would be produced from oxidative phosphorylation?

2. Concept Map: construct a concept map that depicts the metabolism of glucose through glycolysis, the TCA cycle, electron transport and oxidative phosphorylation. For your drawing, include where in the cell these processes occur. The map should show the names of all intermediates (but do not show structures), the names of all enzymes, all products and cofactors required/produced and all membrane complexes. (10) Hint: Include Glucose →glycolysis steps → pyruvate → acetylCoA → TCA cycle steps → electron transport chain...
