Detailed explanation-1: -A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.

Detailed explanation-2: -Cellular respiration that proceeds in the presence of oxygen is called aerobic respiration.

Detailed explanation-3: -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.

Detailed explanation-4: -It is often called aerobic respiration because the process requires oxygen (the root aer comes from the Greek word for “air”). In the absence of oxygen, cells can get energy by breaking down food through the process of fermentation, or anaerobic respiration.

Detailed explanation-5: -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).
