Vedclass · Answer

(A) $Pepsin$ is a proteolytic enzyme secreted by the chief cells of the stomach in the form of an inactive precursor called $pepsinogen$.In the presence of $HCl$ (hydrochloric acid),$pepsinogen$ is converted into its active form,$Pepsin$.$Pepsin$ is highly specific to an acidic environment and shows maximum catalytic activity within the $pH$ range of $1.20$ to $1.80$.If the $pH$ increases significantly above this range,the enzyme becomes inactive.

The digestive enzyme $Pepsin$ functions only in an acidic medium within a limited concentration range. What is its optimal $pH$ range?
