What is Glycogen: Functions and Importance
Subject : Biology
Question:
What is Glycogen?
Expert Verified Solution:
Glycogen is a complex carbohydrate that serves as a key energy reserve in the body. It is primarily stored in the liver and muscles. The main functions of glycogen include:
Energy Storage: Glycogen acts as a major energy source that the body can quickly mobilize when needed. When blood glucose levels drop, glycogen is broken down into glucose, which is then released into the bloodstream to provide energy for various bodily functions.
Energy Regulation: During exercise or between meals, the body breaks down glycogen to maintain blood glucose levels. This process ensures that the body has a steady supply of energy even when intake from food is not immediate.
Supporting Physical Activity: In muscles, glycogen provides the immediate energy needed for high-intensity and prolonged physical activities. This helps athletes and individuals performing strenuous exercises to sustain their performance.
