Vedclass · Answer

(C) Enzymes are biological catalysts that are highly specific in their action $(ii)$.They function by providing an alternative pathway with lower activation energy for the reaction $(iii)$.Pepsin is a well-known proteolytic enzyme that breaks down proteins into peptides $(iv)$.Enzymes possess various functional groups,including nucleophilic groups (like $-OH, -SH, -NH_2$) in their active sites,which participate in the catalytic mechanism. Therefore,statement $(i)$ is incorrect.

Which of the following statements about enzymes are correct?
$(i)$ They lack nucleophilic groups.
$(ii)$ They are highly specific.
$(iii)$ They catalyze reactions by lowering the activation energy of the reaction.
$(iv)$ Pepsin is a proteolytic enzyme.
