Enzymes make biochemical reactions go much faster - the rate is a million to a billion times enhanced.
They act as a catalyst.
Enzymes alter the equilibrium of a chemical reaction by lowering the activation energy required for the reaction to occur, thus speeding up the rate at which the reaction reaches equilibrium. This is achieved by stabilizing the transition state of the reaction, making it easier for the reactants to form products.
the more enzymes, the faster the reaction
The reaction rate is affected by enzymes.
A catalyst alter rate of reaction by lowering the activation
Heat can change the rate of reaction
Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
Why heating enzymes usually produces a faster rate of reaction?
The Reaction Rate
Altering the pH might cause the enzymes involved in a reaction to be denatured. When enzymes are denatured, they do not function properly and the rate of the reaction either slows down or completely stops.
Enzymes lower the activation energy barrier, making it easier for substrates to form products. They do this by providing an alternative pathway for the reaction to occur more quickly. This leads to an increase in the rate of the biochemical reaction.
Enzymes are biocatalysts, they accelerate the reaction rate. Different individual enzymes operate by different mechanisms.
