Question

If I wanted to prepare to run a marathon, what type of macromolecule would I want
to consume?

Answer 1

Complex Carbohydrates

Step-by-step explanation:

There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.
