Explain how the `p^(H)` and concentration of subtrate affect enzyme activity with graphical representation.

Text Solution

Verified by Experts

Effect of `P^(H)` on enzyme activity : Enzymes generally function in a narrow range of `P^(H)`. Each enzyme shows its highest at a particular `P^(H)` called optimum `P^(H)`. Activity decreases both below and above optimum value.

Effect of concentration of substrate on enzyme activity with the increase in substrate concentration, the velocity of enzymatic reaction raises at first. The reaction ultimately reaches a maximum velocity (Vmax) which is not exceeds by further raise in the concentrate of
