Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are carbs stored in animals?
A
Starch
B
Glycogen
C
Cellulose
D
None of the above
Explanation: 

Detailed explanation-1: -Carbohydrates are stored in the form of starch in plants, while in animals, it is stored in the form of glycogen. Glycogen is made up of long polymer chains of glucose subunits bonded together by alpha acetal linkage.

Detailed explanation-2: -In vertebrates it is stored mainly in the liver as a reserve of glucose for other tissues. In hepatocyte cells it is accumulated and mobilized according to blood glucose availability and to extrahepatic cells. Glycogen is also stored in muscles and fat cells.

Detailed explanation-3: -In animal cells, glucose is generally stored in the form of glycogen. This is done to not upset the osmotic balances in the cell. Glucose molecules are soluble in water and thus can cause the cell to become hypertonic. This will result in the entry of water molecules within the cells and cause it to lyse.

Detailed explanation-4: -Glycogen is the storage form of carbohydrates in mammals. In humans, most of the glycogen is stored in skeletal muscles and the liver.
