Biomolecules Review

Long term energy, insulation for the body, and cushioning for vital organs, are all functions of which organic molecule?

• carbohydrate

• fat

• protein

• sugar

Carb-loading is a strategy that marathon runners have been known to do several days before a big race. This involves eating foods high in carbohydrates.

How does this benefit the athlete?

• It increases the number of amino acids available to build muscle mass.

• It increases the starches stored in the athlete's muscles.

• It increases the storage of glycogen for energy in the muscles.

• It increases body fat which warms and protects the muscles.

What is the fundamental element found in all organic compounds studied by chemists?

• carbon

• hydrogen

• oxygen

• nitrogen
