Biology Question on Enzymes
Role of enzyme in reactions:
A
Decrease activation energy
B
Increase activation energy
C
Inorganic catalyst
D
None of the above
Answer
Decrease activation energy
Explanation
Solution
The role of enzymes in reactions is to Decrease activation energy. Enzymes facilitate chemical reactions by lowering the energy barrier (activation energy) required for the reaction to occur, thus increasing the rate of the reaction.
So, the correct option is (A): Decrease activation energy
