Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Excess glucose in the blood is initially stored as ____, a p polysaccharide that can be converted back into glucose when needed.
A
cellulose
B
glycogen
C
insulin
D
starch
Explanation: 

Detailed explanation-1: -Excess glucose is converted to glycogen by insulin. The process is called glycogenesis.

Detailed explanation-2: -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-3: -Our body stores excess glucose as glycogen (a polymer of glucose), which becomes liberated in times of fasting. Glucose is also derivable from products of fat and protein break-down through the process of gluconeogenesis.

Detailed explanation-4: -Glycogen is a glucose polysaccharide occurring in most mammalian and nonmammalian cells, in microorganisms, and even in some plants. It is an important and quickly mobilized source of stored glucose. In vertebrates it is stored mainly in the liver as a reserve of glucose for other tissues.

Detailed explanation-5: -Excess glucose gets stored in the liver as glycogen or, with the help of insulin, converted into fatty acids, circulated to other parts of the body and stored as fat in adipose tissue. When there is an overabundance of fatty acids, fat also builds up in the liver.
