In comparing the functions, inputs, and outputs of the sub-processes of respiration, which statement provides the MOST accurate explanation regarding the flow of energy during respiration?

A. The Calvin cycle produces the same amount of ATP as glycolysis.

B. The electron transport chain produces the same amount of ATP as the Krebs cycle.

C. The electron transport chain produces more ATP than glycolysis or the Krebs cycle.

D. The Calvin cycle produces more ATP than glycolysis or the electron transport chain.

Respuesta :

Answer:

The correct answer is C electron transport chain produces more ATP than glycolysis or the krebs  cycle.

Explanation:

Glycolysis ,krebs cycle and electron transport chain all are the principle steps of cellular respiration.

 During glycolysis  4 molecules of ATP is produced and 2 molecules of NADH is generated

 During krebs cycle 2 molecules of GTP  which is equivalent to 2 molecules of ATP is produced along with 6 molecules of NADH and 2 molecules of FADH2 are produced.

During electron transport chain the 8 molecules of NADH of glycolysis and krebs cycle and 2 molecules of FADH2 of krebs cycle undergo oxidation to form 26 molecules of ATP.
