Question

1. provide a mechanistic explanation for the enhanced rate of muscle glycogen breakdown during exercise. Be sure to address the coordinated effect of both anabolic and catabolic processes in your response.

Answer 1

Glycogen is the main energy source during excercise. Glycogen gets converted into glucose more rapidly in anaerobic condition than aerobic condition , thus providing energy. Majority of glucogen is stored in skeletal muscles and liver. Glycogen thus stored in the tissues prevent the body from getting fatigued .

What happens during excercise?

• muscle glycogen is depleted during excercise.
• high carbohydrate rich makes glycogen available.
• Glucogen available got conveerted to glucose thus providing energy.
• The excess glycogen is stored in the tissues.

In anabolic metabolism, the body uses the available nutrients like proteins to build up new compounds. It strengthens the muscle fibres.

In catabolic metabolism, the body relases out energy by breaking the complex compounds. Sustained excercise can result in catabolism.
