Chapter 26, Problem 8TYR
Summary Introduction
Introduction:
Glycolysis is the process of splitting of glucose molecules by the glycolytic enzymes, and it produces ATP for the immediate energy needs; it also forms the two pyruvate molecules. Anaerobic fermentation leads to the formation of lactate from the pyruvate in the absence of oxygen, along with this regeneration of NAD+ to continue the process of glycolysis without halting.
