Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When animals consume more energy than they use, they are able to store the extra in what two forms?
A
sugar and protein
B
glycogen and fat
C
glucose and starch
D
blubber and cellulose
Explanation: 

Detailed explanation-1: -Energy is stored in the form of glycogen in animals. Excess carbohydrates and proteins get converted into fatty acids and stored in adipose tissues.

Detailed explanation-2: -Glycogen is a homopolysaccharide found in the liver and muscles of animals, where it is used to store energy. Chemically, glycogen is related to starch and closely resembles amylopectin.

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: -Animals store energy in the form of lipids rather than in the form of carbohydrates because lipids have a higher energy content. This is because lipids have a higher ratio of hydrogen atoms to carbon atoms than carbohydrates and the energy content of organic molecules is in the carbon-hydrogen covalent bonds.

Detailed explanation-5: -Since glycogen storage is limited, excess glucose is converted to fat and is stored in adipose tissue. This is accomplished by the breakdown of glucose to pyruvate through a process called glycolysis, which is then available for fat synthesis.
