Scenario
An abundant and continual supply of ATP is necessary for all living cells. Toxins, reduced blood flow, and a compromised respiratory system can interfere with the transport of oxygen to active cells. A runner in a marathon faces multiple obstacles to continue to produce sufficient ATP to remain competitive.
-Exchanges across respiratory membranes are increased when we breathe faster as we exercise. What exchanges are increased, and why?
