Question

based on the figures, why does the coach recommend the students eat foods that are high in starch?
a. it will allow the students to produce more carbon dioxide, which is essential for energy production during a workout.

b. it will allow the students to store more oxygen molecules, which are necessary for cellular respiration during a workout.

c. it will allow the students to store more potential chemical energy, which can be readily converted to usable energy during a workout.

d. it will allow the students to have more glucose molecules stored in their muscles, which directly provide energy without the need for cellular respiration during a workout.

Explanation:

• Option A: Carbon dioxide is a by - product of respiration, not used for energy production. Eliminate A.
• Option B: Starch is not related to storing oxygen. Eliminate B.
• Option C: Starch is a carbohydrate. When consumed, it can be broken down and stored as potential chemical energy (e.g., as glycogen), which can be converted to usable energy (ATP) during workouts via cellular respiration. This makes sense.
• Option D: Glucose is used in cellular respiration to produce energy. Muscles don't store glucose directly in large amounts (they store glycogen), and energy from glucose still requires cellular respiration. Eliminate D.

Answer:

C. It will allow the students to store more potential chemical energy, which can be readily converted to usable energy during a workout.
