Is the optimum pH for rennet acidic or base?
If anything under 7 is acidic and rennet , in its first stage, us 5.8. Then the optimum pH for rennet is acidic
Optimum pH of most enzymes is 7. Optimum pH is pH at which enzyme shows maximum activity . It all depends to the particular enzyme you are talking about, there is no general rule. for example in human pepsin catalyse the reaction at high acidic pH (1.5 to 3) whereas trypsin has optimum pH falls between 7 to 9 (neutral to basic).
