  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true

Show answer
Correct Option: C
Explanation:

Oparin and Sydney Fox held that large organic molecules synthesised abiotically on primitive earth and formed large colloidal aggregates due to intermolecular attraction. These colloidal particles were called coacervates. In coacervates, lipid molecules are joined end to end forming a layer around each aggregate. This represents a single lipid membrane. Coacervates divide by budding like bacteria.

Degradation of proteins play a part in ____________.

  1. Calvin cycle

  2. Water cycle

  3. Sulphur cycle

  4. Nitrogen cycle

Show answer
Correct Option: D
Explanation:
Plants and animals contain nitrogen in their body Protein' After death, the Proteins of dead bodies are decomposed into amino acids and ammonia. This ammonia may be converted into nitrates or free Nitrogen'
So, the correct answer is 'Nitrogen cycle'

Nitrate reductive is classified as a.

  1. Zinc protein

  2. Iron protein

  3. Molybdenum protein

  4. Copper protein

Show answer
Correct Option: A

Those amino acids that cannot be synthesized by the body and must be derived through the diet are known as

evs nutritious food minerals and vitamins nutrition and diet role of various nutrients

  1. coenzymes

  2. essential amino acids

  3. polypeptides

  4. non-essential amino acids

Show answer
Correct Option: B
Explanation:

  • Essential amino acids are not produced in the body, so they are to be taken from outside.
  • There are 9 essential amino acids; Histidine, isoleucine, leucine, valine, threonine, tryptophan, phenylalanine
So, the correct answer is 'Essential amino acids'

Non-protein part of the conjugated protein is called.......

evs nutritious food minerals and vitamins nutrition and diet role of various nutrients

  1. co-factor

  2. ketone

  3. prosthetic group

  4. derivative

Show answer
Correct Option: A
Explanation:

Enzymes with protein and non protein part is called conjugated enzyme. It is also called holoenzyme. In this, protein part is called apoenzyme and non protein part is called co-factor. In the co-factor, organic co-factors are called co-enzymes and inorganic co-factors are called metal ions.

So, the correct option is 'co-factor'.

Which of the following is not a structural protein?

evs nutritious food minerals and vitamins nutrition and diet role of various nutrients

  1. Fibrin

  2. Albumin

  3. Collagen

  4. Keratin

Show answer
Correct Option: B
Explanation:

  • Structural proteins are the proteins that are generally fibrous and stringy. They are the most abundant class of proteins in nature. Their main function is to provide mechanical support. Examples of structural proteins can be keratin, collagen, fibrin and elastin.
  • Albumin is a type of transport protein which help to transport the materials in the cells and form channels in the plasma membrane.
So, the correct option is 'Albumin'.

There are 20 amino acids that act as monomers for producing common proteins.

evs nutritious food minerals and vitamins nutrition and diet role of various nutrients

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

There are 20 amino acids found inside our body. The name of these 20 common amino acids is as follows: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. They get combined in an unlimited number of configurations to construct all the required proteins with which our body is built.

So, the correct option is 'True'.
