The potential of NADH and FADH 2 is converted to more ATP through an electron transport chain with oxygen and protons (hydrogen) as the "terminal electron acceptors". The end result is the production of pyruvic acid. When oxygen is not available? Cellular respiration that does not need oxygen is called anaerobic respiration. Additionally, in what stage of catabolism is the most ATP produced? Glycolysis and ATP Production Glycolysis is produced in a cell's cytoplasm. It is the initial stage of cellular respiration. Glycolysis 2. Animals take in oxygen and give off carbon dioxide. In this stage, energy from NADH and FADH 2 , which result from the Krebs cycle, is transferred to ATP. Why is ATP synthase important in cellular respiration? Glycolysis means the splitting of sugar, and it occurs before any other stage of respiration, regardless of whether or not the process is aerobic or anaerobic. These two molecules then move on to the second phase of the cellular respiration process. Photosynthesis helps plants to store energy in the form of glucose. Carbon dioxide is considered a waste product of cellular respiration. Glycolysis is the set of chemical reactions that takes place in cellular respiration. How does ATP synthase produce ATP in photosynthesis? In cellular respiration, most ATP is produced directly as a result of _____. Electron transport begins with several molecules of NADH and FADH 2 from the Krebs cycle and transfers their energy into as many as 34 more ATP molecules.
