Krebs cycle
4.3 The link reaction and Krebs cycle as stages of aerobic respiration in the mitochondrion

The link reaction
The first stage in respiration, whether it's aerobic or anaerobic, is glycolysis. This produces two molecules of ATP, two
molecules of reduced NAD and two molecules of pyruvate. It…

produces two molecules of carbon dioxide
produces one…
