Pyruvate generated by glycolysis under anaerobic conditions is converted tolactate or ethanol. It may seem this is a waste of energy, but it is in factcritical to survival for cells exposed to oxygen limiting conditions. Explain whythis is true.
The end product of glycolysis, pyruvate, cannot enter as such into the citric acid cycle. Which process converts this C3 compound to a C2 compound?
Why is this reaction crucial to ATP synthesis in glycolysis?
