All EXCEPT one of the following are characteristics of an enzyme?

Question

a) lower the activation energy of a reaction

(b) can be used in many different chemical reactions

(c) involved in but not changed by the reaction

(d) allow chemical reactions to occur at moderate temperatures

Answer 1

the answer is B

enzymes are very specific in their structure - which makes them sensitive to only specific substrate.... which makes them usable only for one reaction.  That is why our body produces many different enzyme for many different  reactions. If there is missing or defective enzyme, we suffer with metabolic disorders (such as phenylketonuria)
