If levels of ____ and/or ____ are low, pyruvate is directed primarily into ____; but if they are high, pyruvate is converted into ____ for gluconeogenesis.

Question

Quizplus · Accepted Answer

If ATP levels are high, it indicates that there is sufficient energy available and pyruvate is directed towards the TCA cycle via the conversion into acetyl coenzyme A. If acetyl CoA levels are high, it indicates that the TCA cycle is already producing energy and pyruvate is also directed towards the TCA cycle via the conversion into oxaloacetate. Thus, both high ATP and high acetyl CoA levels direct pyruvate towards the TCA cycle, while low levels of these molecules signal that more energy is needed and so pyruvate is directed towards glycolysis to produce more ATP.
