Assertion (A): Lactic acid bacteria cause chemical changes in milk during curd formation. Reason (R): LAB produce enzymes that directly ferment lactose without producing acids.
View solution & NCERT explanation
Correct answer: C — If assertion is true but reason is false.
NCERT confirms LAB cause chemical changes in milk (Assertion true). However, NCERT states “During growth, the LAB produce acids that coagulate and partially digest the milk proteins” - the Reason incorrectly describes direct enzyme action on lactose without acid production, making it false. The actual mechanism involves acid production that causes protein coagulation.
