Answer #1

  • ATP is formed by ATP synthase during - oxidative phosphorylation - The oxidative phosphorylation is a process that occur at mitochondrial inner membrane in which electrons are carried through a series of electron carries and protons are pumped into inner membrane space. This proton gradient is used to synthesize ATP.

  • In substrate-level phosphorylation - ATP is formed from ADP and inorganic phosphate by an enzyme - The synthesis of ATP that occurs in metabolic reactions and not involving electron carriers is called substrate level phosphorylation, because a substrate having high energy is brought to low energy by an enzyme and the released energy is used to produce ATP from ADP and inorganic phosphate.

Mitochondria produce most of the cell's ATP by oxidative phosphorylation. Electrons from NADH and FADH2 formed in the TCA cycle are transported through the electron transport chain (ETC) which consists of four complexes (I, II, III and IV). Hereby, a proton gradient is formed across the inner membrane of the mitochondria which is used by the ATP synthase to form ATP. In isolated mitochondria, oxygen consumption rate (OCR) and rate of ATP synthesis can be determined, respectively. Seahorse and NOVOstar...

Glycolysis, the TCA cycle and oxidative phosphorylation are tightly coupled by allosteric inhibition or stimulation of various enzymes in the pathways. Among the compounds that act as inhibitors or stimulators are glucose 6-phosphate, ADP, AMP, Pi (inorganic phosphate ion), ATP, citrate, NADH, and succinyl-CoA. For as many steps in the pathways as you can, indicate which enzymes or reactions are inhibited or stimulated by which of the compounds listed. A given enzyme reaction may be stimulated or inhibited by more...
