Question

Which structure level enables proteins to function as enzymes?

• A. Primary
• B. Secondary
• C. Tertiary
• D. Quarternary

Answer 1

The correct option is C Tertiary

Enzymes are generally tertiary in structure because it allows easy binding of the cofactor. The tertiary structure is the three dimensional conformation of proteins. The folded peptide chain are stabilized by chemical bonds. Hydrogen bond, ionic bond, disulphide linkage and hydrophobic interaction stablizes the structure.

So, the correct answer is option C.
