Question

Biochemistry question:
Which statement is not associated with covalent catalysis by enzymes?

Answer 1

A transient covalent bond is formed between the enzyme and the substrate.
It never involves coenzymes.
When the reaction is complete, the enzyme returns to its original state.
A new pathway from substrate(s) to product(s) is formed that is faster than the uncatalyzed reaction.

I'm thinking it's the second statement? (it never involves coenzymes)

Answer 2

Correct.
Covalent catalysis involves the formation of a reversible covalent bond between the enzyme and substrate. Enzymes performing covalent catalysis bear nucleophilic or electrophilic centres.
