Enzymes have a 3D shape due to which type Of protein structure:
Correct answer: C. Tertiary structure
- A. Primary structure
- B. Secondary structure
- C. Tertiary structure
- D. Quaternary structure
Explanation
Enzymes have a three-dimensional shape due to their tertiary structure. This structure is formed by the folding and twisting of the polypeptide chain, which is determined by the interactions between amino acids. The specific shape of enzymes is crucial for their function, as it allows them to bind with substrates and catalyze chemical reactions. So, the tertiary structure is like the unique "lock and key" that enables enzymes to carry out their important roles in our bodies.

About Classification of Proteins
Proteins are classified by composition as simple, conjugated and derived proteins, and by shape as fibrous or globular proteins. The topic relates these classes to examples such as albumin, keratin, collagen, haemoglobin and casein, while distinguishing structural proteins from proteins with transport, catalytic or regulatory roles.
