During the action of ATP synthase, the kinetic energy of the proton gradient is transformed into potential energy.
In what organelle is acetyl-CoA synthesis carried out in a cell?
Fermentation produces nearly two times as much ATP as aerobic respiration, which explains why it is a preferred pathway for bacteria.
Which of the following is not one of the net final products of glycolysis?
