Answer:
In the absence of oxygen, fermentation releases energy from food molecules by producing ATP.
Explanation: By fermentation releasing food molecules it allows for ATP to begin.
A runner continues to make atp when her oxygen is limited by:
Adenosine Triphosphate (ATP) is the primary center where energy is found in the cells. This ATP transports energy to the other parts of the body from the food particles and helps in the processes of the cell.
As a result of this, when a runner's oxygen is limited, she begins to make up ATP through a process called fermentation where the food particles are released to the blood stream.
