  1. Secretion of lactic acid

  2. Formation of milk

  3. Absorption of milk

  4. Absorption of fat


Correct Option: D

Which of these is not a ketone body

  1. Acetoacetic acid

  2. Acetone

  3. Succinic acid

  4. Betahydroxy butyric acid


Correct Option: C
Explanation:

In human and most other mammals, acetyl Co-A formed in the liver during oxidation of fatty acids can enter the citric acid cycle or can be converted to the "Ketone bodies" (e.g., Acetone, Acetoacetate and D - $\beta $ hydroxy butyrate) for export to other tissue.

  2. Pancreatic and intestinal juices

  3. Pancreatic and bile juices

  4. Bile and intestinal juices

  1. Lipase

  2. Bilirubin and biliverdin

  3. HCl

  4. Sodium salts of glycoholic and taurocholic acid

After surgical removal of infected gall bladder, the person should be careful in intake of

  1. Fat

  2. Sugar

  3. Starch

Fats serve as the best storage of spare energy becuase

  1. Fats yield double amount of energy yielded by glucose on oxidative breakdown

  2. Fats can be stored in an almost pure unhydrated form

  3. Fats accomodate in lesser space

  4. All the above


Correct Option: A
Explanation:

Fat is an essential part of our diet and is important for good health.

fat is the major storage form of energy in the body. These are found in plant foods and fish. Fats help in the absorption of fat-soluble vitamins A, D, E, and K. 

So, the correct option is ‘Fats yield the double amount of energy yielded by glucose on oxidative breakdown’.
