WebJan 4, 2024 · The Krebs cycle happens in our cells across the inner membrane of the mitochondria — the organelles responsible for cellular power production. Cellular … WebDuring cellular respiration, the energy from glucose is released in the presence of oxygen. This process is scientifically known as aerobic respiration. Anaerobic respiration occurs in the absence of oxygen. Aerobic Respiration Glycolysis, Krebs cycle, and electron transport chain are the three steps of aerobic respiration.

WebLiving 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 … WebBecause the Krebs cycle needs NAD+, NAD+ is generated by the electron transport chain and the transport chain requires oxygen. Thus if the transport chain stops because of anaerobic condition, no NAD+ is generated = Krebs cycle cannot happen.
