Question

Sort the physical activities into their respective bins based on the primary energy source used during the activity.

a) Carbohydrates
b) Fat
c) ATP
d) Creatine Phosphate

Answer 1

Physical activities can use carbohydrates and fat as primary energy sources, depending on the intensity. Creatine phosphate is another energy source for short bursts of activity.

Step-by-step explanation:

In physical activities, the primary energy source can vary depending on the intensity of the activity. Low-intensity activities primarily use aerobic metabolism, which relies on carbohydrates to supply ATP to the muscles. High-intensity activities, on the other hand, require more ATP and rely on both carbohydrates and fat for energy. Additionally, creatine phosphate can supply energy to working muscles at a very high rate, but only for a short period of time.
