WebThe Krebs cycle occurs as part of both cellular respiration and photosynthesis. Oxygen and water are produced in the Krebs cycle. The Krebs cycle is the final step in cellular respiration. Not all living things engage in the Krebs cycle. Question 12 30 seconds Q. In what part of the cell does the Krebs cycle take place? answer choices mitochondria Web(which occurs during glycolysis and the Krebs Cycle). Oxidative phosphorylation is the most effective method for producing ATP because it makes use of the proton gradient to create a greater quantity of ATP. This makes it the most efficient pathway for producing ATP. When ATP is created directly from the breakdown of a molecule, a route known ...
