- D III, IV
Answer & Solution
Correct Answer
(C) I, IV
Step-by-step Solution
Detailed explanation
(i) Binding of inhibitor at allosteric site changes the shape of the active site in such a way that substrate cannot recognise it. (ii) Shape of the receptor changes after attachment of chemical messenger to it. (iii) A chemical messenger gives message to the cell without…
