If so, how does it get out of the mitochondrion to go be used as energy? This set of reactions uses the enzyme RuBP carboxylase to react with carbon dioxide. Corrections? This is in contrast to the highly efficient process of aerobic respiration, which relies on oxygen to produce energy. Learn more about how oxidative phosphorylation uses electron transport to drive ATP synthesis. Cellular respiration must use the process of glycolysis to transfer energy. Much more ATP, however, is produced later in a process called oxidative phosphorylation. NADH and FADH2 carry electrons on to the electron transport system. First, all the food you eat has to be broken down into glucose, a type of sugar, which is then broken down into even smaller molecules. What is the role of NAD+ in cellular respiration. It is used in breathing, flattening as it contracts and causing the lungs to expand. Learn. Therefore, at the end of two cycles, the products are: two ATP, six NADH, two FADH, and four CO2. Because two acetyl-CoA molecules are produced from each glucose molecule, two cycles are required per glucose molecule. The krebs cycle is the process that follows glycolysis during cellular respiration. A portion of the air you breathe never reaches the alveoli. When they do not get enough oxygen, the cells use anaerobic respiration, which does not use oxygen. It happens when an enzyme takes a phosphate molecule from an intermediate and gives it to ADP, creating an exergonic reaction. Science Photo Library - MIRIAM MASLO.
