I HAVEN'T A CLUE??!?!?!

1 answer:

7 0

Answer:

The higher the altitude the lower the air pressure and therefore the lower the oxygen levels. Low oxygen means low oxygen is getting to the lungs and into the blood and into tissues. Therefore Krebs cycle becomes ineffective in generating ATPs, the energy currency of cells. Mountain climbing is a physically extraneous exercise hence energy is required by the body yet the cells are no producing enough ATPs.

This effect is similar to cyanide permanently binding to Cytochrome c oxidase that catalyzes the reduction of oxygen as the ultimate electron and proton acceptor in the Krebs cycle. Oxygen reduction is significant in the generation of ATPs in the mitochondria.
