Question

Quizplus · Accepted Answer

Enzymes are known for their ability to catalyze specific reactions, meaning that they are very selective in the substrates they can bind to and convert.

The other statements are false. Enzymes are organic molecules made up of proteins (and sometimes non-protein components known as cofactors). Enzyme function is affected by changes in pH and other environmental factors. And not all enzymes require protein cofactors – some require non-protein cofactors like vitamins or metals.
