Students were asked to design a lab that investigated the relationship between heart rate and exercise. Heart rate was determined by recording the pulse rate in beats per minute. The students hypothesized that increased exercise results in an increased heart rate. The class results for the experiment are shown above.

reduces the rate at which oxygen is carried to the muscles cells

Answer 1

The most appropriate response to the question regarding the change in heart rate that occurs between 1 and 5 minutes of exercise is:

results in the production of more ATP in muscle cells.

During exercise, the body requires more energy to support increased activity, leading to an increase in heart rate. This increased heart rate enhances blood flow, which delivers more oxygen and helps generate more ATP (adenosine triphosphate) through cellular respiration in muscle cells.
