Question

An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provided energy. Which two biomolecules mus the supplement contain to provide these benefits?

a. Carbohydrates and lipids

b. Proteins and carbohydrates - correct

c. Nucleic acids and carbohydrates

Answer 1

The supplement has to build lean muscle and strengthen tendons and ligaments. Muscle, tendons, and ligaments are all made of protein. So the supplement must contain protein.

It should also provide energy. The most readily used form of energy is carbohydrates (for energy metabolism, carbs are used first, then lipids, then proteins as a last resort). Therefore, the supplement should have carbohydrates.

B is wrong because it does not have any protein to build muscle, tendon, or ligament with.
