Question

Match List-I(enzymes of pathogen) with List-II(host substrates) and select the correct answer.

List-I	List-II
a. Pectin methyl esterase	$1$. Linear anhydroglucose chain
b. Cx enzyme	$2$. Pectic acid
c. Polygalacturonase	$3$. Native cellulose
d. $C_1$ enzyme	$4$. Pectin

• A. A-$4$, B-$3$, C-$2$, D-$1$
• B. A-$4$, B-$1$, C-$2$, D-$3$
• C. A-$2$, B-$3$, C-$4$, D-$1$
• D. A-$2$, B-$1$, C-$4$, D-$3$

Answer 1

The correct option is A A-$4$, B-$3$, C-$2$, D-$1$

Pectin methylesterase act on pectin, involved deesterification of methyl esterified D galactosiduronic acid. Cx enzyme is cellulolytic enzyme,that involved in hydrolysis of native cellulose. polygalacturonase is a hydrolytic enzyme act upon polygalacturonic acid also called pectic acid.C1 enzyme involved in degradation of native cellulose into linear anhydroglucose chain. So option A is correct answer.
