Question

At the “Metabolism Magic” booth, nutrition students explain how your body can convert extra sugar from a meal into fat for long-term energy storage. This process happens naturally in your liver and fat cells. What important principle about life’s building blocks does this metabolic conversion demonstrate?
Question 5 options:

Sugar molecules and fat molecules are actually exactly the same type of molecule

CHON elements can be rearranged and reassembled to make different molecules as needed

This conversion is impossible since each molecule type is completely separate and different

Only sugar molecules can be converted to other molecules, while fats cannot change

Answer 1

CHON elements can be rearranged and reassembled to make different molecules as needed.

Explanation: metabolism breaks sugar down (e.g., to acetyl‑CoA) and uses those carbon, hydrogen, and oxygen atoms to build fatty acids and triglycerides. The atoms are conserved and simply rearranged into new molecules.
