Question

Assertion: Co-enzyme is a non-protein group without which certain enzymes are inactive or incomplete.

Reason: Co-enzymes not only provide a point of attachment of the chemical group being transformed but also influence the properties of the group.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is: (a)

Explanation:

Some enzymes depend for activity only on their structure as proteins, while others require in addition nonprotein structures or cofactor for activity. The cofactor may be either a metal ion or a complex organic molecule called a coenzyme usually function as intermediary carriers of electrons or of specific atoms or functional groups that are transferred in the overall enzymatic reaction.
