Question
Chapter 17, Problem 10P
Interpretation Introduction
Interpretation:
The purpose of the remaining steps in the pyruvate dehydrogenase reaction cycle other than the formation of acetyl Co A.
Concept introduction:
Pyruvate dehydrogenase enzyme complex is required for the linking of glycolysis and TCA. It helps in the conversion of pyruvate into Acetyl CoA. Acetyl CoA then enters into the series of the citric acid cycle.

- This is an application question. You are not expected to know anything about the regulation of pyruvate dehydrogenase. Cellular respiration is regulated at many points in the pathway. When ATP levels are high in the cell, NADH molecules accumulate and bind to pyruvate dehydrogenase (the enzyme complex involved in the oxidation of pyruvate) at a site other than the active site to prevent the conversion of pyruvate into acetyl-CoA.

- Which statement does NOT describe a general function of the pentose phosphate pathway? Group of answer choices The pentose phosphate pathway is used to produce NADPH for reductive biosynthesis in adipocytes. The pentose phosphate pathway allows for the entry of dietary pentose intermediates into the glycolytic pathway. The pentose phosphate pathway produces reduced molecules whose electrons may be shuttled to the mitochondria for oxidative phosphorylation. The pentose phosphate pathway allows for the conversion of hexoses into pentoses that may be used as precursors in the synthesis of nucleosides.arrow_forwardUse your knowledge of fat metabolism. glycolysis, the TCA cycle, and axidative phosphorylation to determine how many molecules of ATP eauvalents are produced when glycerol undergoes biochemical combustion.
