Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP

A. Transport from complex I produces more ATP.

B. Transport from complex II produces more ATP.

C. Both produce the same amount of ATP.

Answer :

Smberensongo

Answer:

A

Explanation:

ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.

Electron transport from complex I produces more ATP.

ELECTRON TRANSPORT CHAIN:

  • The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration.

  • The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis.

  • The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers.

  • Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space.

  • Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.
