Question
Chapter 24.3, Problem 24.7P
Interpretation Introduction
Interpretation:
The effect of high level of citrate on the rate of glycolysis needs to be determined.
Concept introduction:
The main regulatory enzymes of glycolysis are hexokinase, pyruvate kinase and phosphofructokinase.
In case of citric acid cycle, the enzyme pyruvate dehydrogenase is turned off when fatty acids and acetyl CoA are in high concentrations. The enzyme is turned on when requirement of acetyl CoA is high and when there is high energy demand.
The other three enzymes which are regulated includes - alpha ketoglutarate dehydrogenase, isocitrate dehydrogenase and citrate synthase. The enzyme citrate synthase varies according to the
