ATP is produced by oxidative phosphorylation in
ATP is produced by oxidative phosphorylation in
Open in App
Solution
The correct option is D Chemiosmosis.
Glycolysis and Kreb's cycle form total 4 ATPsby substrate level phosphorylation wherein the direct transfer of phosphate group to ADP or GDP during chemical reactions leads to the synthesis of ATP/GTP. Oxidative phosphorylation is the process wherein oxidation of reducing equivalent generate energy to drive ATP synthesis. Chemiosmosis includes the use of proton gradient generated across the inner mitochondrial membrane, during transfer of electrons from NADH and FADH2 to O2, to drive ATP synthesis. During chemiosmosis, 10 molecules of NADH power synthesis of 10*3 = 30 ATP while 2 molecules of FADH2 power synthesis of 2*2 = 4 ATP.Thus, the correct answer is option C.
