Answer:

Starch

Explanation:

Pasta is made of eggs and flour. The eggs are basically water, proteins and fats while flour is composed by starch.

Starch is a macromolecule that is composed of two polysaccharides, amylose and amylopectin, which are big chains of glucose, so starch is a carbohydrate. Carbohydrates are the biggest source of energy to the body, then, the starch will be the molecule in the pasta that increases the runner’s energy.

Bear in mind that proteins and fats also give energy but, as the starch is in greater proportion it will provide more energy to the runner.
