Which of the following best explains why "carbs" (carbohydrates) are advertised by manufacturers of candy bars and sports drinks as a "quick energy boost"? Select one:a. This is an advertising gimmick that has no scientific evidence to support it. b. Carbs are reduced molecules that have high-energy electrons. c. The energy in them can be stored as fat, which has high energy per unit weight. d. The carbons in carbs are rich in energy because they are highly oxidized

The correct option is B.

Explanation:

Carbohydrates are the major macro molecules that are used as a source of fuel in biological systems. The smallest unit of carbohydrate is glucose and this is the only macro molecule that biological systems can use to produce energy. Other macro molecules such as fats and proteins can be converted to glucose if their is shortage of glucose in the body.

Generally, carbohydrates have high level of energy in their reduce electrons, thus, when they are oxidized they give rise to large amount of energy, which can be used to do work in the biological systems.
