Enzyme reaction activity refers to the speed at which enzymes catalyze (speed up) chemical reactions in living organisms. It is influenced by various factors, including temperature.
Activation energy is the minimum amount of energy required for a chemical reaction to occur. It acts as a barrier that must be overcome before a reaction can proceed.
Denaturation occurs when high temperatures or extreme pH levels cause an enzyme to lose its shape and function. It's like a chef who becomes so overwhelmed with heat that they forget how to cook properly.
