Question

Which part of cellular respiration produces the most ATP?

Answer 1

The electron transport chain of the cellular respiration process produces maximum ATP.

There are three parts of cellular respiration:

   1.Glycolysis

which produces 2 ATP.

   2.Krebs cycle

which does not produce any ATP. It produces only the raw materials for ATP production.

   3.Oxidative phosphorylation (electron transport chain )

It produces maximum ATP. It takes one NADH molecule via Channel 1 to produce 2.5 ATP and one FADH2 molecule via channel 2 to produce 1.5 ATP, for a total of 34 ATP.

Answer 2

Which part of cellular respiration produces the most ATP?

Glycolysis, which produces 2 ATP.

Krebs cycle, which does not produce any ATP. It produces only the raw materials for ATP production.

Oxidative phosphorylation, which involves the electron transport chain that produces maximum ATP.

or

The electron transport chain is a series of molecules embedded in the mitochondrial membrane uses the high-energy electrons from the krebs cycle to convert ADP to 34 ATP. At the end of the chain the spent electrons join with H+ ions and oxygen to make molecules of water
