When yeast cells are switched from aerobic to anaerobic growth conditions, the rate of glycolysis increases. The rate of glycolysis is regulated by the concentration of _______ in the cells.

Question

Quizplus · Accepted Answer

The rate of glycolysis is regulated by a negative feedback mechanism where an increase in ATP concentration inhibits the enzymes involved in the process. Therefore, in anaerobic conditions where less ATP is being produced, the concentration of ATP decreases, leading to an increase in the rate of glycolysis.
