A tiger is running across a field. What would happen if the hydrogen ion pumps in the tiger's mitochondria stopped functioning?

A. The tiger would be unable to eat any food.
B. The tiger would have a sudden burst of energy.
C. The tiger would not be able to produce glucose.
D. The tiger would not be able to keep running

Respuesta :

D. The tiger would not be able to keep running

Answer:

(D). The tiger would not be able to keep running

Explanation:

The hydrogen ion pumps present in mitochondrial inner membrane, generate proton gradient  across the mitochondrial membrane.

Proton pumps are very important for the process of electron transport chain as it enables synthesis of energy molecules or ATPs by using electrochemical gradient formed by movement of protons.  

So, if hydrogen ion pumps are not functioning in tiger's mitochondria, he would not be able to produce energy and he would be unable to keep running.

Thus, the correct answer is option (D).
