Item EB078001: Students who are running experience sweating, increased heart rate, and increased breathing rate because of an increase in the rate of cellular respiration that is needed to get the energy required to run.
During physical education class, several students ran a mile race. After their run, the students recorded changes they experienced. The students noticed that after the run they were sweating, their faces were flushed, their hearts were beating faster, and they were breathing faster.
Why did the students experience these changes after running? Your answer should describe the role of matter and energy changes during running and include what happens at the molecular, cellular, and organ/organ system levels of biological organization.
