The process that uses energy stored in a hydrogen ion gradient across a … How many ATP are made in the electron transport part of cellular respiration? The Krebs cycle ends in a complete breakdown of the glucose molecule. Start studying Cellular Respiration 2.06 FLVS (80%). Cellular Respiration Stage III: Electron Transport Electron transport is the final stage of aerobic respiration. A mitochondrion is an organelle within a eukaryotic cell. Uses of Cellular Respiration Plants and animals both use cellular respiration to perform life functions on a daily basis. The second phase, or the Krebs cycle, begins when the pyruvate molecules enter the mitochondrion. The first phase of cellular respiration is glycolysis, which involves splitting glucose. They are: 1. 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". What is the formula for cellular respiration? Plants use it to perform photosynthesis, which provides the sustenance they need to stay alive. This delicate balance makes animals and plants dependent on each other for survival. Glycolysis is the set of chemical reactions that takes place in cellular respiration.
