BIOMOLECULES AND ENZYMES

Detailed explanation-1: -During moderate-intensity exercise, roughly half of the energy is derived from glycogen, while the other half comes from glucose in the blood and fatty acids. Carbohydrates (glucose/glycogen) serve as the primary source of fuel as duration and intensity increase.

Detailed explanation-2: -Carbohydrate is an important energy source during exercise. During short, heavy exercise it may be the only energy source for the working muscle and may be derived exclusively from the glycogen stores within the muscle fibers themselves.

Detailed explanation-3: -The Master Fuel. A diet rich in carbohydrates increases both endurance and intermittent high-intensity performance because of the extra store of carbohydrates in the muscles and liver, called glycogen.

Detailed explanation-4: -For athletes, a high-carb diet is needed in order to sustain the daily demands of training and exercise. While the needs will vary based on the individual and the type of exercise or sports they engage in, carbs will always make up a majority of calories.

Detailed explanation-5: -Carbohydrates are the main energy source of the human diet. The metabolic disposal of dietary carbohydrates is direct oxidation in various tissues, glycogen synthesis (in liver and muscles), and hepatic de novo lipogenesis.
