WebMaking ATP Without Oxygen Living things’ cells power their activities with the energy-carrying molecule ATP (adenosine triphosphate). The cells of most living things make ATP from glucose in the process of cellular respiration . This process occurs in three stages: glycolysis , the Krebs cycle , and electron transport . WebRespiration releases energy from glucose in the form of ATP. This occurs in all living cells. Aerobic respiration (with oxygen) releases more energy than anaerobic respiration (without oxygen).
WebOct 23, 2024 · This is why air-breathing organisms die so quickly without a constant supply of oxygen: our cells cannot generate enough energy to stay alive without it. Instead of oxygen, anaerobic cells use substances such as sulfate, nitrate, sulfur, and fumarate to drive their cellular respiration.
