|
| C |

|
| D |
Inhibits protein synthesis |
Ans. is ‘a’ i.e., Binds to -SH group of enzyme
- Heavy metal toxicity is caused by tight binding of a metal such as mercury (Hg), lead (Pb), aluminium (Al), or iron (Fe) to a functional group of enzyme.
- Mercury, for example, binds to reactive sulfhydryl groups (-SH) in the active site of so many enzymes, that it has been difficult to determine which of the inhibited enzyme is responsible for mercury toxicity.
- Lead also has high affinity for sulfhydryl group.
