Answer 1

Answer:

B. The bird will stop flying because it will quickly use up its remaining

energy.

Explanation:

This is because the mitochondria is known as the power house of cells. Oxidative phosphorylation takes place in this organelle and it involves the conversion of ADP to ATP through the hydrogen ions(protons).

When the hydrogen ion channel is blocked, energy production in cells stop.

This is why the bird will stop flying as it would have used up its remaining energy and won’t have a new one to use to continue flying.
