Question

What is NOT a way that enzymes speed reactions?

Answer 1

Hey there!!

• An enzyme is an organic catalyst. But both have the same task which is to speed up the reaction.
• There are three way by which a reaction could be made quicker.
• By increasing concentration
• By increasing temperature
• By using a catalyst.
• A catalyst speeds up the reaction by lowering the activation energy.
• Activation energy is the energy needed in order to start a reaction.

Hope my answer helps!

Answer 2

. The active site can provide heat from the environment that raises the energy content of the substrate.

An enzyme cannot extract heat from the environment to speed a reaction. It can only lower the activation energy barrier so that more substrates have the energy to react.
