Among the following vegetarian food items, which one is
considered to be more rich in proteins

  1. Bread

  2. Rice

  3. Potato

  4. Pulses


Correct Option: D
Explanation:

Pulses are the rich sources of protein whereas bread, rice and potato are rich in carbohydrate and starch.

So the correct option is D.

Assertion : Coacervates are believed to be the precursors of life.

Reason : Coacervates were self - duplicating aggregates of proteins surrounded by lipid molecules.

  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


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


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


Correct Option: A

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

  1. coenzymes

  2. essential amino acids

  3. polypeptides

  4. non-essential amino acids


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'
