Question

animals release energy needed for growth and repair through a (1 point)
● a series of chemical reactions during cellular respiration
○ a series of chemical reactions that change light energy into sugars
○ a series of chemical reactions during photosynthesis
○ a series of chemical reactions that change carbon dioxide and water into sugars

Explanation:

To solve this, we analyze each option:

• Option 1: Cellular respiration in animals breaks down glucose to release energy (ATP) for growth, repair, etc. This is correct.
• Option 2: Converting light energy to sugars is photosynthesis (done by plants, not animals' energy - release for growth/repair). Eliminate.
• Option 3: Photosynthesis is for plants to make food, animals don't do photosynthesis. Eliminate.
• Option 4: Converting CO₂ and water to sugars is photosynthesis (plant - based), not how animals release energy for growth/repair. Eliminate.

Answer:

a. a series of chemical reactions during cellular respiration
