Glycolysis

Detailed explanation-1: -In tissues with high energy requirement, such as heart, up to 50–70% of energy, in the form of ATP production, comes from fatty acid (FA) beta-oxidation .
Detailed explanation-2: -The metabolic cycle that provides the highest net ATP per glucose molecule is oxidative phosphorylation.
Detailed explanation-3: -The mitochondrion performs most cellular oxidations and produces the bulk of the animal cell’s ATP. The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle.
Detailed explanation-4: --oxidation is the catabolic process by which fatty acid molecules are broken down to generate acetyl-CoA and NADH and FADH2, which are used in the electron transport chain for ATP production.
Detailed explanation-5: -Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen. Anaerobic respiration uses chemicals other than oxygen, and this process is primarily used by archaea and bacteria that live in anaerobic environments.
