Detailed explanation-1: -The gas oxygen is essential to perform cellular respiration and obtain energy from your food. 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: -Oxygen is required in the cellular respiration in the electron transporter chain. It serves as the final electron acceptor of the electron transport chain facilitating the movement of electrons down the chain hence producing the ATP or adenosine triphosphate.
Detailed explanation-3: -Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).
