Question

Statement 1: Enzyme reaction is dependent of concentration on enzyme only and not substrate.

Statement 2: Do enzymes catalase and peroxidase show residual enzyme activity?

(a) True, False

(b) True, True

(c) False, False

(d) False, True

This question was addressed to me in a national level competition.

This interesting question is from Principles of Food Preservation by Drying-2 topic in chapter Principles of Food Preservation by Canning and Drying and Principles of Food Concentrates of Food Engineering

Answer 1

The correct option is (d) False, True

For explanation: Enzyme reaction is dependent on the concentration of both, enzyme and substrate. Enzymes catalase and peroxidase show residual enzyme activity unlike other enzymes when subjected to harsh conditions like low moisture environment.
