Question

how do the cells in your body use the molecules they get from food?
a. the cells use the molecules as a source of energy and matter.

b. the cells use the molecules to eliminate bad gases in the body.

c. certain cells in the body take the molecules and turn them into
cells.

d. the cells use the molecules to carry out the process of
photosynthesis.

Explanation:

• Option A: Cells break down food molecules (like glucose) to get energy (e.g., through cellular respiration) and also use the molecules as building blocks (matter) for growth, repair, and synthesis of new molecules.
• Option B: Eliminating "bad gases" is not the primary use of food molecules by cells; gas exchange (like removing CO₂) is part of respiration but not the use of food molecules.
• Option C: Cells don't "turn food molecules into cells" directly; they use molecules for energy and to build cell components, but the process is more about metabolism than direct transformation into cells.
• Option D: Photosynthesis is done by plants (using chloroplasts), not animal cells (which don't have chloroplasts).

Answer:

A. The cells use the molecules as a source of energy and matter.
