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

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.

  1. Fat

  2. Sugar

  3. Starch

  4. Protein

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’.

Energy content of alcohol is $7.1kcal/gm$. it is more than carbohydrates and slightly less than fats. Intake of alcohol provides

  1. Enough energy to body for its working

  2. Releases heat energy

  3. Uses energy of body for dissipation of alcohol produced heat

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alcohol metabolism releases energy as heat, but it also increases the body's metabolic rate and heat dissipation processes, which can lead to a net loss of body heat or energy imbalance.

An example for essential fatty acids

  1. Glutamic acid

  2. Aspartic acid

  3. Linoleic acid

  4. Tartaric acid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them. Two essential fatty acids, linolenic and linoleic acid, cannot be synthesized in the body and must be obtained from food. These basic fats, found in plant foods, are used to build specialized fats called omega-3 and omega-6 fatty acids.

Each fat molecule is formed from 

  1. One glycerol molecule and one fatty acid molecule

  2. One glycerol molecule and three fatty acid molecules

  3. Three glycerol molecules and one fatty acid molecule

  4. Three glycerol molecules and three fatty acid molecules
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fatty acids are long, straight chain carboxylic acids. A fat molecule is formed when three fatty acids molecules combine with one glycerol molecule to yield a triglyceride (another name for fat) along with three water molecules. Fats are not easily digested and are transported and stored as triglycerides.

So, the correct option is 'One glycerol molecule and three fatty acid molecules'.
