Detailed explanation-1: -Aerobic respiration requires the presence of oxygen to produce energy from food. It is the most common type of respiration seen in plants and animals.

Detailed explanation-2: -Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.

Detailed explanation-3: -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-4: -Comparison chart. Aerobic respiration uses oxygen. Anaerobic respiration is respiration without oxygen; the process uses a respiratory electron transport chain but does not use oxygen as the electron acceptors. Aerobic respiration occurs in most cells.
