If I exercised at a high intensity for 5 minutes, at that point, what would be contributing the most energy production?
A. Glucose in the Liver
B. Glycogen in the Liver
C. Glycogen in the Liver
D. FFA in the blood
Answer : Glycogen in the liver
Explanation : during high intensity exercise the body needs instant energy resource. Carbohydrate gives instant energy while fat gives energy slowly.
Excess amount of glucose is stored as Glycogen in liver and muscle cells. Hence, when someone do intense exercise the Glycogen ( stored form of carbohydrate in animals) breaks down and provides energy to the individual.
If someone will do exercise for a long time, than the stored fat provides them energy.
Glucose is not present in liver while FFA is present in blood plasma and causes insulin resistance to organs leading to obesity and have no relationship with providing energy to the individual.
Also the muscles contains more Glycogen than the liver. As Glycogen in humans is stored in skeletal muscles and liver.
