The Steps of Glycolysis
Captions available
The idea
Glycolysis proceeds through an energy-investment phase and an energy-payoff phase, ten enzyme-catalyzed steps carrying one glucose molecule to two molecules of pyruvate.
Where people slip
Glycolysis pays back its own two-ATP investment before it profits — the pathway's four gross ATP nets down to two.
