Answer:
c. excessive glucose is present in the blood
Explanation:
Glycogen is the energy currency for intense physical activity. It is a set of glucose molecules available to generate immediate energy.
The two "deposits" of glycogen are the liver and muscle. While practicing sports, it is important to use one source or another, since they have different functions.
Of the total glycogen stored in a 70 kg subject, approximately 400-500 grams, about 400 grams correspond to muscle glycogen, and 80-100 grams to liver glycogen.
Muscle glycogen
It must supply the needs of the muscle during sports activity. Glycogen storage in muscles is systematically depleted during exercise. The depletion rate depends on the intensity of the exercise and the amount of glycogen stored in the muscles before starting the workout.
Liver glycogen
It regulates the concentration of blood glucose, and it is this glucose that feeds the brain constantly (the brain has no reserves and can only use glucose as a source of energy).
The glycogen stores in the liver are higher after meals but decrease between them and especially during the night and fasting, since liver glycogen is degraded to maintain normal blood glucose levels.
