Question

1. as food moves through a series of chemical reactions in the body __

○ the atoms that make up the food molecules are destroyed and energy is created.
○ the molecules that make up the food are broken down and new atoms are created.
○ the atoms that make up the food molecules are rearranged, and energy is released.
○ the molecules that make up the food are destroyed and new energy is created.

Explanation:

1. Analyze the first option: Atoms are not destroyed in chemical reactions (conservation of mass), and energy is not "created" but transformed, so this is incorrect.
2. Analyze the second option: Atoms are not created in chemical reactions (conservation of mass), so this is incorrect.
3. Analyze the third option: In metabolic processes (like digestion and respiration), food molecules are broken down, atoms are rearranged (forming new molecules), and energy stored in bonds is released (e.g., ATP production), which follows the law of conservation of mass and energy transformation.
4. Analyze the fourth option: Molecules are broken down (not destroyed) and energy is transformed, not "created", so this is incorrect.

Answer:

C. the atoms that make up the food molecules are rearranged, and energy is released. (Note: Assuming the third option is labeled C; adjust the label based on the original question's numbering if different, but the content is "the atoms that make up the food molecules are rearranged, and energy is released.")
