Which best details the movement of energy through aerobic cellular respiration?

• Heat energy is absorbed as chemical potential energy is transferred from oxygen molecules to ATP molecules.

• Heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules.

• Heat energy is absorbed as chemical potential energy is transferred from ATP molecules to glucose molecules.

Brenda ran a 5 km race. During the race, she began to breathe heavily, and some of her muscles began to burn. Which of these explains why Brenda felt a burning in her muscles during the race?

• The cells did not have enough oxygen, so they used fermentation as a source of energy.

• The cells did not have enough glucose, so they used fermentation as a source of energy.

• The cells had too much glucose, so they used aerobic respiration as a source of energy.
