Why do humans need to eat ridiculous amounts of food to build muscle, but Gorillas are way stronger by only eating grass and fruits?

Question

Why do humans need to eat ridiculous amounts of food to build muscle, but Gorillas are way stronger by only eating grass and fruits?

In: Biology

Answer 1

Gorillas produce protein in their guts on their own. We as humans don’t do that. We produce glucose and the some(not all) of protein we eat is converted into glucose and used to fuel our muscles. Most of it is used to make new proteins to strengthen our bones, muscles, etc.
