Explanation / Answer

4) Correct option is B

A 12 stranded beta sheet containing 6 consecutive parallel strands from the first subunit and the 6 consecutive parallel strands with opposite polarity from the second subunit.

5) Correct option is C

2,2,2 trifluoroethanol and NAD are fully burried in the binding site while the bound Zn extends to the surface of the protein.

6) Correct option is C

Multiple bridged hydrogen bonds
