Excess carbohydrates and proteins are stored in body as

  1. Amino acids

  2. Fats

  3. Monosaccharides

  4. Starch

B Correct answer
Explanation

The excess carbohydrates and proteins are stored in the body as fats. It gets converted into energy during excessive physical work. Essential fatty acids are those fatty acids which play an important role in the biological process and they can be metabolized easily. These acts as a fuel rather getting deposited as fat in the body. The human body cannot synthesize essential fatty acids. Unsaturated fats are liquid at room temperature as they have double bonds. The essential fatty acids are unsaturated as they have double bonds. Saturated fatty acids have the single bond and are solid at room temperature.

So, the correct answer is option B.

D Correct answer
Explanation

While glycogen is used for short term energy storage in the liver and muscles, fat is the primary form for long term energy storage in the body due to its high energy density.

  2. Formation of milk

  3. Absorption of milk

  4. Absorption of fat

D Correct answer
Explanation

Lacteals are specialized lymphatic capillaries located in the villi of the small intestine that absorb dietary fats (chylomicrons) that are too large to enter the blood capillaries directly.

Which of these is not a ketone body

  1. Acetoacetic acid

  2. Acetone

  3. Succinic acid

  4. Betahydroxy butyric acid

C Correct answer
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.

Emulsified fats are digested by

  1. Gastric juice and pancreatic juice

  2. Pancreatic and intestinal juices

  3. Pancreatic and bile juices

  4. Bile and intestinal juices

B Correct answer
Explanation

Emulsified fats are primarily digested in the small intestine by pancreatic lipase and intestinal lipase, which break them down into absorbable components.

Fatty substances are emulsified by

  1. Lipase

  2. Bilirubin and biliverdin

  3. HCl

  4. Sodium salts of glycoholic and taurocholic acid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bile salts, specifically sodium glycocholate and sodium taurocholate, act as detergents to emulsify fats, increasing the surface area for lipase action.

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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’.
