Your friend is on the cross country running team. They tell you they need to "carbo-load" ahead of their big race in a couple days as they want to store extra carbohydrates in their muscles. 1. Identify what macromolecule should they eat more of over the next couple of days? Identify that molecule's function.

2. Identify what food from the selection should they eat. (Hint: There is more than one correct answer)

3. Explain how you know that food has the macromolecule they need. (Think about what test will you use to support your statement)

This question is incomplete

Explanation:

This question is incomplete because of the absence of some options

1. There are four major macromolecules found in nature; Carbohydrates, proteins, lipids and nucleic acid. The macromolecule that assists with the production of energy for immediate energy and glycogen storage (which is the storage of "energy" in the muscle) is carbohydrates.

2. The foods that should be selected here are food that are rich in carbohydrate. Examples of such food include Rice, cassava, yam and plantain.

3. To test for the presence of carbohydrate in the food sources chosen in (2) above, iodine test can be used. The choice of iodine test is because the food sources mentioned above contains complex carbohydrates. Few drops of a solution of iodine should be added to a sample of the food, if the colour of the iodine on the sample turns blue black, then that confirms the presence of complex carbohydrates in the food.

i think it is true in my reasonment ..
