Question

You’re now in the Health & Nutrition section of the science fair, where local culinary students, health science programs, and nutrition clubs have set up interactive booths. They’re demonstrating cooking experiments, testing food samples, and showing how the basic chemicals of life work in everyday foods we eat. As you help visitors understand these displays, you’ll need to use your knowledge of biochemistry.
Question 4 (11.111111111 points)

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 4 options:

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

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

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

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

Answer 1

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

Explanation: Metabolism breaks sugars down (glycolysis → pyruvate → acetyl‑CoA) and uses those carbon and hydrogen atoms to build fatty acids and triglycerides. This shows that the same basic elements (C, H, O, N) can be reorganized into different biomolecules rather than being fixed to one molecule type.
