The change in heart rate that occurs between 1 and 5 minutes of exercise is an adaptation that: ) reduces the rate at which oxygen is carried to the muscle cells(2) increases the rate at which carbon dioxide is carried to the muscle cells(3) results in the production of more atp in muscle cells(4) slows the destruction of enzymes involved in respiration of muscle cells

(3) results in the production of more ATP in muscle cells

Explanation:

When exercising, Oxygen is introduced to the muscle cells via the Red Blood Cells. Hemoglobin which is carried by the Red Blood Cells binds with these oxygen to to supply the muscle cells with oxyenated blood. Thus, as blood flows into the muscle cell during exercise, there is increase in the rate at which oxygen is carried to the muscle cells.

On the otherhand, Carbondioxide is not carried to the muscles cells but it is diffused out of the bloodstream as bicarbonate ion (HCO⁻₃).

The change in heart rate that occurs between 1 and 5 minutes of exercise is an adaptation that: results in the production of more ATP in muscle cells. Thi s is becuase, Adenosine triphosphate (ATP) is a  compound with high potential energy. The  synthesize ATP molecules in the muscle cells is gotten  from complex  molecules such as carbohydrate, proteins and fats. So during exercise, there are more production of more ATP in the muscle cells to assist in the degradation of carbohydrate, proteins and fats that give rise to pyruvate, amino acids and fatty acids respectively.
