Words and meanings to learn
optimum pH
the pH at which an enzyme-substrate reaction works best at.
active site
the part of the enzyme which is responsible for binding and breaking down the substrate.
denature
when the enzyme's active site changes shape so it can no longer bind with the substrate and produce a product.
initial rate of reaction
the start of the reaction; this is usually the fastest part of the reaction.
rate of reaction
a measure of the breakdown of reactant or the formation of product over a unit of time.
