Answer:
A. The molecule to which a drug binds
Explanation:
The correct answer is aerobic conditions.
When you do rigorous exercise, the cells of the muscles require more oxygen and this requirement is met through aerobic conditions.
The body has its own oxygen energy system that manages the presence of the oxygen during movement.
The correct answer is...Once the enzyme binds to the specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.
