Web17 feb. 2024 · ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis. The majority of ATP synthesis occurs in cellular respiration within the mitochondrial matrix: generating approximately thirty-two ATP molecules per molecule of glucose that is oxidized. Web4 jun. 2024 · Since 1929, when it was discovered that ATP is a substrate for muscle contraction, the knowledge about this purine nucleotide has been greatly expanded. Cellular respiration is the process of catabolizing glucose into acetyl-CoA, producing high energy electron carriers that will be oxidized during oxidative phosphorylation, yielding ATP.
