Question

Proteins after digestion are converted into:

• A. Carbohydrates
• B. Small globules
• C. Amino acids
• D. Starch

Answer 1

The correct option is C

Amino acids

The correct option is C.

Explanation of the correct option:

1. The amino acids are the building blocks of proteins.
2. Amino acids are linked by peptide bonds which make up the nascent protein and do not have any functional properties.
3. Further, this nascent protein undergoes folding and gains functionality.
4. The folding happens because of the residual charges residing in the protein forming strong and weak bonds such as disulfide bonds, hydrogen bonds, Van-der walls interaction, ionic interaction, and hydrophobic interaction.
5. Hence proteins are regarded as complex molecules for which amino acids are the basic components.

Explanation of the incorrect options:

Option A:

1. Carbohydrates are the macromolecules of sugars.
2. Hence, the breakdown of starch yields carbohydrates.

Option B:

1. Small globules are the smaller units of fats.
2. They are formed as a result of the breakdown of fats.

Option D:

1. Starch is a complex carbohydrates molecule.
2. It is present in plants when they store their food.

Final Answer: Proteins, after digestion, are converted into Amino acids.
