Question

Cells produce ATP both aerobically and anaerobically. One process is an integral part of aerobic respiration that produces the majority of ATP molecules isA) glycolysis. B) fermentation C) the Krebs cycle. D) the electron transport chain.

Answer 1

D.) the electron transport chain produces the most ATP

Answer 2

Answer: The electron transport chain.

Explanation: An electron transport chain can be defined as a series of complexes that aids in the transfer of the electrons from the donor to the acceptor, by the process of redox reaction with the transfer of H+ ions across the membrane.

This forms an electrochemical proton gradient that helps in the synthesis of ATP that stores energy in the bonds.

The maximum number of ATPs are produced by ETC. From a single glucose molecule 38 ATPs are produced, out of which 34 are produced by ETC and rest of the 4 are produced by the process of glycolysis( 2ATP) and Kreb's Cycle (2 ATP).
