Actually, enzymes are typically used to catalyse a biological reaction, leading to a faster reaction rate, not slower.
No, the sole purpose of enzymes are to increase the rate of a chemical reaction. Even if they are not at an optimal temperature, they will not slow down the reaction. They won't work as efficiently, but it will still be slightly faster than without the enzymes.
the more enzymes, the faster the reaction
The reaction rate is affected by enzymes.
Heat can change the rate of reaction
Why heating enzymes usually produces a faster rate of reaction?
The Reaction Rate
Enzymes are biocatalysts, they accelerate the reaction rate. Different individual enzymes operate by different mechanisms.
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
Enzymes are considered to be catalysts; they increase the rate of a chemical reaction.

The reaction rate is affected by enzymes.
Enzymes control the rate of chemical reactions by lowering the activation energy required for the reaction to occur. This enables reactions to proceed at a faster pace and with more specificity than without enzymes. Enzymes do not change the overall equilibrium of a reaction.
