ANATOMY

Detailed explanation-1: -Final answer: Aerobic respiration occurs in presence of oxygen.

Detailed explanation-2: -The Presence of Oxygen There are two types of cellular respiration: aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis-the splitting of glucose. Glycolysis is an anaerobic process-it does not need oxygen to proceed.

Detailed explanation-3: -Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Detailed explanation-4: -Aerobic respiration requires the presence of Oxygen.
