Which of the following statements about enzyme substrate complexes is TRUE?

A. At high substrate concentration the rate of the reaction is first order.

B. The enzyme concentration is higher than the substrate concentration under physiological conditions.

C. Alteration in the conformation of the enzyme may occur when substrate binds.

D. Increase in enzyme concentration does not affect the rate of the reaction.

For the regulation of the glycolysis pathways, what the molecules involved are and how they act.

What is the goal of glycolysis? What are the original reactants and final products

how many atp are consumed by the glycolysis of a single molecule of glucose

When would serine 32 be phosphorylated, during glycolysis or gluconeogenesis?

Please use this discussion to explain Glycolysis how you understand it.

b) Explain the advantages and disadvantages of glycolytic metabolism (anaerobic glycolysis).

During strenuous activity, the demand for ATP in muscle tissue is vastly increased. In rabbit leg muscle or turkey flight muscle, the ATP is produced almost exclusively by lactic acid fermentation. ATP is formed in the payoff phase of glycolysis by two reactions, promoted by phosphoglycerate kinase and pyruvate kinase. Suppose skeletal muscle were devoid of lactate dehydrogenase. Could it carry out strenuous physical activity; that is, could it generate ATP at a high rate by glycolysis? Explain.

Discuss the pros and cons of lactate production in active muscle. Why is lactate produced? What happens to the lactate?

The transformation of glucose to lactate in myocytes releases only about 7%
of the free energy released when glucose is completely oxidized to CO₂ and H₂O. Does this mean that anaerobic glycolysis in muscle is a wasteful use of glucose?
