What do amino acids, fatty acids, and sugars have in common?

Question

1. used to store energy
2. used to make proteins.
3. Made from carbon, oxygen and hydrogen
4. They are all produced during photosynthesis.

Answer 1

Amino acids, fatty acids, and sugars share the commonality that they are all made from carbon, oxygen, and hydrogen. Therefore, the correct answer from your options is:

3. Made from carbon, oxygen and hydrogen.

While they can be involved in energy storage and metabolism, not all of them serve the same primary roles (for example, amino acids are primarily building blocks for proteins, whereas fatty acids are involved in energy storage and membrane structure), and not all are produced directly during photosynthesis.
