Question

which process do animals use to convert energy from food into atp? a. cellular respiration b. osmosis c. photosynthesis d. transcription

Explanation:

To solve this, we analyze each option:

• Option A: Cellular respiration is the process by which cells (including animal cells) break down food molecules to produce ATP, the energy currency of the cell.
• Option B: Osmosis is the movement of water across a semi - permeable membrane, not related to energy conversion from food to ATP.
• Option C: Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy (glucose), and animals do not perform photosynthesis.
• Option D: Transcription is the process of copying DNA into RNA, which is related to gene expression, not energy conversion from food to ATP.

Answer:

A. cellular respiration
