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

Explanation:

• Cellular respiration is a series of chemical reactions, not a single one. So the first statement is false.
• As per the given text, cellular respiration releases energy. So the second statement is true.
• The text clearly states that cells use energy - rich molecules (like sugar) in cellular respiration. So the third statement is true.
• Cellular respiration occurs inside cells. So the fourth statement is false.

Answer:

B. Cellular respiration releases energy.
C. Cellular respiration uses energy - rich molecules.
