Answer: Her body begins doing cellular respiration

Explanation: She needs her electron transport chain to function to produce 34+ ATP. The E.T.C. Needs oxygen to work, so she needs to increase her oxygen input. She breathes more to increase the flow of oxygen. Her heart also beats faster because she needs more oxygen to spread to her body.
