Energy Sources and Systems
- Carbohydrates are the preferred source of fuel during exercise.
- The primary function of protein in the body during exercise is to provide amino acids for muscle repair and development.
- Adenosine triphosphate (ATP) is the molecule that supplies energy to muscle cells for muscular contraction during physical activity.
- The glycolytic system is the energy system that involves the breakdown of glucose and is controlled by enzymes.
- The citric acid cycle, also known as the Krebs Cycle, is a key energy system that generates energy for the body during exercise.
