Question

when an animal eats, certain food molecules undergo change inside the animals body. the diagram shows a formula for this process.
glucose
oxygen
carbon dioxide
water
+
→
+
+
energy
based on the diagram, what happened to the food molecules?
choose the correct answer.
they combined with water to release energy.
they reacted with energy from sunlight to form sugars.
they rearranged to form new molecules and release energy.

Explanation:

1. Analyze the first option: The diagram shows glucose (food molecule) reacting with oxygen, not water, to release energy. So this option is incorrect.
2. Analyze the second option: The process shown is cellular respiration (in animals), not photosynthesis (which uses sunlight to form sugars in plants). So this option is incorrect.
3. Analyze the third option: The glucose (food molecule) and oxygen react, and the atoms rearrange to form carbon dioxide and water (new molecules), and energy is released. This matches the diagram of cellular respiration.

Answer:

They rearranged to form new molecules and release energy.
