During a running race, a person’s breathing rate and heart rate increase. These changes most directly help the person do which of the following? Increase the rate of digestion. Decrease the rate of gamete production. Decrease the rate of protein synthesis in neurons. Increase the rate of cellular respiration in mitochondria.
Understand the Problem
The question is asking about the physiological changes that occur during a running race, specifically how an increase in breathing rate and heart rate is related to cellular respiration in mitochondria. This is focused on understanding the body's response to physical activity.
Answer
Increase the rate of cellular respiration in mitochondria.
The final answer is to increase the rate of cellular respiration in mitochondria.
Answer for screen readers
The final answer is to increase the rate of cellular respiration in mitochondria.
More Information
During physical activity, increased breathing and heart rate deliver more oxygen to cells. This oxygen is used in cellular respiration, a process in mitochondria that produces energy. This energy powers muscles during intense activity like running.
Tips
A common mistake is to confuse the direct impact of increased breathing and heart rate with less related processes like digestion or protein synthesis.
