Question

1. what happens to the chemical energy in food after you eat it?

a. cellular respiration converts the energy to a usable form.
b. cellular respiration destroys the energy in the food.
c. the energy is converted into matter during cellular respiration.
d. the energy is not changed in any way during cellular respiration.

Explanation:

To solve this, we analyze each option:

• Option A: Cellular respiration is the process by which cells convert the chemical energy in food (like glucose) into ATP, a usable form of energy for cellular activities. This matches the role of cellular respiration.
• Option B: Energy is not destroyed; it's transformed (law of conservation of energy), so this is incorrect.
• Option C: Energy is not converted into matter; cellular respiration converts chemical energy to ATP (energy form), not matter.
• Option D: The energy changes from stored chemical energy in food to usable energy (ATP) during cellular respiration, so this is wrong.

Answer:

A. Cellular respiration converts the energy to a usable form.
