During a high-energy athletic event, such as a sprint, most of the energy that is provided to the muscles comes from
A.glycolysis.
B.the electron transport chain.
C.the Krebs cycle.
D.fermentation.
(CORRECT ANSWER IS B JUST TOOK TEST)--

Respuesta :

Electron transport chain

Answer:

B. the electron transport chain

Explanation:

Electron transport chain is the final step of aerobic cellular respiration that produces a large number of ATPs by using the energy of proton motive force as generated during oxidation of NADH and FADH2.

Sprint needs a high amount of energy and muscles of athletes are conditioned to carry out aerobic cellular respiration during sprints to avoid any lactic acid accumulation due to fermentation.
