Answer:
A is correct...B and C wrong I believe
Explanation:
So basically the reason A should be correct is because all enzymes do is provide alternative mechanisms for reaction to proceed and in that alternative mechanism the activation energy is lowered allowing the reactions to progress at greater speeds.
So A makes sense because The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move (basically like an enzyme the car's shape is allowing the car to move faster... enzymes are not consumed in a reaction; they simply help it to occur.)
B is not correct because enzymes do not provide energy for reaction to occur. All they provide is an alternate mechanism where the activation energy is lowered so the reactions can occur at greater rate.
C is not correct because some reactions can occur without enzymes its just that they will occur at a much slower speed.
Hope this helps! I think this should be correct plz double check with your friends.
