Question

cells take in small, energy - rich molecules from food. these molecules include sugar molecules.
cells use the molecules in a long series of chemical reactions. these reactions are known together as cellular respiration. cellular respiration breaks down energy - rich molecules to form different molecules. this process also releases energy.
which of the following statements are true about cellular respiration? select all that apply.

• cellular respiration happens outside of cells.
• cellular respiration uses energy - rich molecules.
• cellular respiration is a single chemical reaction.
• cellular respiration releases energy.

Explanation:

The text states cellular respiration is a series of chemical reactions inside cells that uses energy-rich molecules (like sugars) and releases energy.

Answer:

B. Cellular respiration uses energy-rich molecules, D. Cellular respiration releases energy
