Detailed explanation-1: -The ATP synthase isolated from bovine (Bos taurus) heart mitochondria is, in terms of biochemistry and structure, the best-characterized ATP synthase. Beef heart is used as a source for the enzyme because of the high concentration of mitochondria in cardiac muscle.
Detailed explanation-2: -The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.
Detailed explanation-3: -In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes-glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation-to produce ATP.
Detailed explanation-4: -ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (Pi) through oxidative phosphorylation, which is a process in which enzymes oxidize nutrients to form ATP. ATP synthase is found in all lifeforms and powers all cellular activities.
Detailed explanation-5: -The ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
