Explanation:

Proteomics is the cataloging and analyzing every protein in the human body most proteins differ in their folding manner .

Identify the incorrect match between the protein and its role.

  1. Keratin structural component of hair

  2. Immunoglobulins protection of body against diseases

  3. Haemoglobin transport of $O _2$ in muscles

  4. Thrombin blood clotting

Show answer
Correct Option: C
Explanation:
The pigmented proteins in the muscle fibers which impart the red color to the muscles is called myoglobin. This protein is involved in the process of oxygen storage in the muscle tissues by binding to it. In conditions such as hypoxia oxygen is released by the myoglobin. Hence it is the oxygen trasnsporter to the muscle fibers. Thus the correct answer is option C. 

Nails, hair and feathers are made of

evs - i constituents of food dietary sources of proteins types of nutrients calorific value of nutrients

  1. Albumin

  2. Keratin

  3. Collagen

  4. Elastin

Show answer
Correct Option: B
Explanation:

Keratin is a simple fibrous protein, which is made up of only amino acids. It forms external protective structures of animals like hair, feathers, nails, horny layer of skin. Thus, the correct answer is B.

Besides having C, H, O which of the following also contains
N, S, p etc.

evs - i constituents of food dietary sources of proteins types of nutrients calorific value of nutrients

  1. Protein

  2. Fat

  3. Carbohydrate

  4. Vitamin

Show answer
Correct Option: A
Explanation:

Proteins are large molecules of high molecular weight containing C, H, O and nitrogen (N) . The presence of N distinguishes them from carbohydrate and fat. Iron, copper, iodine, sulphur and phosphorus may also be present in a very low proportion. Proteins are found in fish, meat, egg, wheat, bean, ground-nut and pulses.

The following is a storage protein

evs - i constituents of food dietary sources of proteins types of nutrients calorific value of nutrients

  1. Keratin

  2. Collagen

  3. Glutelin

  4. Haemoglobin

Show answer
Correct Option: C
Explanation:

A) Keratin is the protein that is the structural material making up hair, horns, claws, hooves and the outer layer of human skin.

B) Collagen is the building block of the entire body, from the skin to the gut.
C) Glutelin is the storage protein that is found in the species of grass family commonly known as gluten.
D) Haemoglobin is a blood protein that helps in the transport of oxygen.
Hence, the correct answer is 'Glutelin'.
