Chapter 15: Q14P (page 521)

What is the advantage of activating pyruvate kinase with fructose-1, 6-bisphosphate?

Short Answer

Expert verified

Fructose-1,6-bisphosphate acts as a feed-forward for the pyruvate kinase.

Step by step solution

01

Glycolysis

One molecule of glucose is transformed into two molecules of pyruvate during the process known as glycolysis. Glycolysis is a series of ten enzyme-catalyzed reactions. Overall, 2 ATP is created; throughout this process, 2 NAD+ is converted to 2 NADH.

02

Advantage of activating pyruvate kinase with Fructose-1,6-bisphosphate

The result of the third glycolysis step is fructose-1, 6-bisphosphate, which activates pyruvate kinase. FBP is a feed-forward stimulant in a glycolytic pathway intermediate because it increases allosteric activation and pyruvate kinase activity as its concentration increases.

Hence, the final six stages of glycolysis are pushed forward towards completion by this regulatory mechanism.

Nerve cells require a source of free energy to transport vesicles containing neurotransmitters along the length of the axon, where mitochondria are scarce. Explain why it makes sense that glyceraldehyde3-phosphate dehydrogenase is located on the surface of some transport vesicles.

Which products of glycolysis are reduced molecules that the cell can oxidize to recover free energy?

What compounds with high phosphate group-transfer potential are synthesized during glycolysis?

Compare the ATP yields and rates of ATP production for anaerobic and aerobic degradation of glucose.

The reversible reaction shown here is part of the Calvin cycle, a pathway in photosynthetic organisms. Which glycolytic reaction does this reaction resemble and what type of enzyme catalyzes it?
