LIFE SCIENCE

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 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: -Aerobic Respiration-Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.

Detailed explanation-4: -Respiration using oxygen to break down food molecules is called aerobic respiration . ‘Aero’ means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration-it is the main respiratory substrate .
