What happens if oxygen is absent in cellular respiration?
When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP.
Which metabolic pathway can occur in the absence of oxygen?
Anaerobic- a metabolic pathway that takes place in the absence of oxygen. It consists of the the 10 steps of glycolysis which breaks down glucose to two molecules of pyruvate.
