Detailed explanation-1: -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-2: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. 8.

Detailed explanation-3: -During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates. Also in the process of cellular respiration, oxygen gas is required to serve as an acceptor of electrons.

Detailed explanation-4: -The end electron acceptor of the electron transport chain is oxygen. Oxygen collects two electrons and also two hydrogen ions from the mitochondrial matrix and forms water. This allows the electron transport chain to keep flowing and creating the gradient necessary to produce ATP.

Detailed explanation-5: -The oxygen that is used in cellular respiration primarily comes from the atmosphere. In cellular respiration, oxygen is used as the terminal electron acceptor of the mitochondrial electron transport chain.
