Sucrose hydrolysis gives:

Reducing sugar:

Number of chiral centers in glucose:

Zwitterion of an amino acid:

Number of standard amino acids in proteins:

Vitamin K is essential for:

Number of H-bonds in G-C base pair:

Assertion (A): Sucrose is a non-reducing sugar. Reason (R): Both anomeric carbons of glucose and fructose are involved in the glycosidic bond — no free anomeric C remains.

Assertion (A): Enzymes are highly specific. Reason (R): Each enzyme has a specific 3D active site that matches only certain substrates (lock-and-key or induced fit model).
