Question

What are amino acids and what is their function in cells?

I - Amino acids are the subunits of proteins.
II - All amino acids have a carboxyl group and an amino group, both attached to their alpha carbon atom.
III - The properties of the side chains of amino acids are the basis of the diversity and sophistication of protein functions.
IV - Proteins are the main building blocks of cells and participate in almost all cellular functions.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only I, II, and III are correct.
d) Only II, III, and IV are correct.
e) All statements are correct.

Ed · Answer

Amino acids are the building blocks of proteins and are essential for many cellular functions. All amino acids have a carboxyl group and an amino group, both attached to their alpha carbon atom. The properties of the side chains of amino acids are the basis of the diversity and sophistication of protein functions. Proteins are the main building blocks of cells and participate in almost all cellular functions. Therefore, all statements (I, II, III, and IV) are correct. The correct answer is (e) All statements are correct.
