How many different types of reactions can an eznyme facilitate? (Types, not total number)
A
1
B
Infinite
C
17
D
Depends on the enzyme
Explanation: 

Detailed explanation-1: -Enzymes are involved in most of the biochemical reactions that take place in organisms. About 4, 000 such reactions are known to be catalyzed by enzymes, but the number may be even higher.

Detailed explanation-2: -Can ONE Enzyme carry out 100 different reaction? No, Enzymes are very specific, it would be 100 different enzymes for 100 different reactions.

Detailed explanation-3: -The first EC number classifies the enzyme reaction mechanism into six groups, namely oxidation–reduction, transition, hydrolysis, dissociation, isomerization and synthesis (creating new chemical bonds with the initial assistance of ATP). Examples of enzymes classified by EC number are: EC 1.

Detailed explanation-4: -An enzyme will interact with only one type of substance or group of substances, called the substrate, to catalyze a certain kind of reaction.
