Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
1 Aerobic respiration uses NADH to produce large amounts of ATP in the presence of oxygen (releasing NAD+). 2  In the absence of oxygen, the NADH remains idle and cannot be used to release NAD+. 3  This means glycolysis cannot occur (no spare NAD+) and no ATP can be produced.
