During exercise, the body primarily relies on energy from carbohydrates, fat, adenosine triphosphate (ATP), and creatine phosphate (CP) in varying combinations depending on the type of physical activity. Consider the various activities below and sort them based on the primary energy source used during the activity. Match the activity with the correct source of energy. Sources of energy - ATP-CP; Carbohydrates, FatActivities - a marathon; a block start in 50-M freestyle; a 5-KM run; a soccer match; an all day walkathon

Yuliana Simpson · Answer 1

1. A block start in 50M freestyle:ATP-CP

2. An all day walkathon - Fats

3. A marathon - carbohydrates and ATP-CP

4. A soccer match - carbohydrates and fats

5. A 5KM run - carbohydrates

Explanation:

Creatine phosphate, CP is a small source of energy which depletes ver fast but is backed up by ATP storage. This is why they are used in very low exercises that is, it can be resynthesized to ATP by the enzyme creatine kinase to replenish depleted ATP levels.

But the major sources of energy during exercise are carbohydrates and fats.

During the medium to low intensity exercise, the bulk of energy required by the muscle is provided by oxidation of fatty acids while for high intensity exercises, carbohydrates are needed so as to be broken down to give glycogen with the generation of ATP.
