Question

during a period of intense activity, such as when an animal runs away from a predator, oxygen levels in the body decline. as oxygen becomes limited, cells in the body switch from performing aerobic respiration to performing anaerobic respiration. what is a consequence of this switch?

a. the animal can begin consuming carbon dioxide rather than producing it.

b. the animal can begin producing oxygen rather than consuming it.

c. the animal receives more energy from each glucose molecule it breaks down.

d. the animal receives less energy from each glucose molecule it breaks down.

Explanation:

La respiración aeróbica produce más ATP (energía) por molécula de glucosa que la respiración anaeróbica. Cuando el cuerpo cambia a la respiración anaeróbica por falta de oxígeno, obtiene menos energía por molécula de glucosa.

Answer:

D. The animal receives less energy from each glucose molecule it breaks down
