Question

Experiments were carried out to investigate the effect of different $pH$ values on enzyme activities. (Time and temperature was kept constant)
(a) What interpretation can you draw from the graph?
(b) What happens to the pepsin reaction between $pH4$ and $5$? Why?
Observe the given graph and answer:-

Answer 1

The graph shows the relation between pH and enzymatic activity. Both Pepsin and Amylase show their maximum activity at pH 2.5 and 7.5 respectively. However, pepsin shows definite dormancy at pH 4 and 5 which means it becomes inactive at this pH level.
