3 is false.
Enzymes don't PROVIDE the activation energy for the reaction. Enzymes do REDUCE the amount of activation energy necessary for the reaction to happen.

answer C is pretend. Enzymes decrease the activation power necessary for reactions to take position. If a lot less power is necessary to commence a reaction it ought to take position much better immediately. The enzymes do no longer easily provide the activation power itself.

3 is wrong....enzymes lower the activation energy but do not produce it.
