BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In humans, ∼80% of the glycogen is stored in skeletal muscles, simply because skeletal muscles account for ∼40–50% of body weight in healthy young men and the glycogen concentration is 80–150 mmol kg ww−1 (Ivy et al., 1988; Hawley et al., 1997; Jensen et al., 2011).

Detailed explanation-2: -Glycogen is a ubiquitous fuel source stored in the cytosol of cells, occupying 2% of the volume of cardiac cells, 10 1%–2% of the volume of skeletal muscle cells, and 5%–6% of the volume of liver cells.

Detailed explanation-3: -Glucose is the main source of fuel for our cells. When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-4: -It appears that the maximal attainable glycogen concentration in human muscle seems to be close 4 g per 100 g wet muscle.

Detailed explanation-5: -Your body mainly stores glycogen in your liver and skeletal muscles (the muscles attached to your bones and tendons), with small amounts in your brain.
