Triglyceride metabolism to convert fats into carbohydrates is helped by glyoxylate cycle. The organelle responsible for this is found in

  1. Rice seeds

  2. Caster seeds

  3. Wheat seeds

  4. More than one option is correct
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The glyoxalate cycle converts the fats into carbohydrates. This takes place in the organelles which are known as peroxisomes.

the lipids that are present in the cell are used to make energy.
This is found in many plants. This cycle is essential for seed germination.
So, the correct option is 'More than one option is correct'

State whether the following statements are true or false.
Lacteals absorb digested fat in the form of chylomicrons.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A lacteal is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. These chylomicrons then pass into the lacteals, forming a milky substance known as chyle.

So, the correct option is 'True'.

Main difference between brown fat and white fat is that the cells of brown fat

  1. Are multicoloured

  2. Have more mitochondria

  3. Are polygonal in shape

  4. All the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Brown fat cells are specialized for thermogenesis and contain a high density of mitochondria, which give the tissue its characteristic brown color. White fat cells primarily store energy and have fewer mitochondria.

The most abundant lipid in the cell membrane is:-

  1. Cutin

  2. Phospholipid

  3. Glycolipid

  4. steroid
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The most abundant lipid present in the cell membrane is phospholipids.
  • The cell membrane is called lipid bilayer as it is a double layer membrane made up of phospholipids. 
  • Phospholipids consist of a polar head group and non-polar fatty acid tails. 
  • The arrangement of these phospholipids in the cell membrane makes the cell membrane permeable.
  • The correct answer is OPTION B.

Quasi-fluid nature of membrane is due to

  1. Phospholipid

  2. Integral protein

  3. Peripheral protein

  4. Sugar moiety
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The presence of Quasi-fluid nature of cell membrane is due to Phospholipids such as cholesterol moieties that impart fluidity.

It allows lateral movement of protein moieties throughout the lipid bilayer.
So, the correct option is 'Phospholipid'.

A pound of butter contains more usable energy than a
pound of sugar for a human because

  1. Sugar contains much more water than butter

  2. A fat molecule has more carbon-hydrogen bonds than a

    sugar molecule

  3. The butter is an animal product, where as the sugar is a

    Plant Product

  4. There is much more waste in digestion and absorption

    of sugar than of butter
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A pound of butter contains more usable energy than a pound of sugar for a human because a fat molecule has more carbon-hydrogen bonds than a sugar molecule. Butter contains fat molecules and sugar contains carbohydrates. Fat molecule have low ratio of oxygen and hydrogen comparison to carbohydrates and they have more carbon-hydrogen bonds than carbohydrates.
