Hence, the main objective of this stage is to use the pyruvates to produce more ATP. Glycolysis (sugar splitting) involves three key stages: Substrate level phosphorylation - The glycose has two phosphate groups added to it from two ATP molecules. Oxygen is absent when this form of respiration takes place. out of the matrix and into the inner-membrane space. Energy stored by NAD+ and FAD (also known as electron carriers or hydrogen carriers) is transferred to oxygen crossing protein channels resulting in ATP synthesis (ATP synthase), Electrons from NADH and FADH are carried through each stage to produce energy; there are 12 loaded electrons at the end of the cycle. Where does the oxygen required for aerobic respiration enter the body? The major energy yield of aerobic respiration takes place in the mitochondria. With a net gain of 2 ATP only in the previous stage, that is ‘glycolysis’, there is the need to harvest more energy. During this stage, each glucose molecule splits in half, forming two molecules of pyruvate. It can be found in the cytoplasm and the mitochondria.
