Is the enzymes affected temporarily or permanents?

Answer 1

That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.

Answer 2

Enzymes can be affected temporarily or permanently, depending on the nature of the change that occurs. Temporary effects can include reversible inhibitors that bind to the enzyme but can be removed, while permanent effects can result from irreversible inhibitors or alterations to the enzyme's structure.
