Answer #1

Sol: 1. In ATP, ADP and AMP, phosphate group is attached with ribose sugar with Phosphodiester bond. So an ester linkage is present. Correct option is b.

2. Conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is an oxidation reaction. So correct option is c.

3. An organism must have 20 types of tRNA corresponding to 20 types of amino acids. So the correct option is d.

4. Open chain form of aldopentose have 2 chiral carbons so correct option is a.

5. Eukaryotic cells are well developed and advanced cell. These have true nucleus. So their DNA is present in their nucleus. So the correct option is d.

6. The enzyme used in the reactions of gluconeogenesis is pyruvate carboxylate. So the correct option is d.
