At the low temperature, a particular enzyme catalyses a reaction best explains temperature affects the function of this enzyme.
Explanation:
Enzymes are those catalysts which is generally proteins through some RNA molecules as enzymes too. The activation energy of reaction of Enzymes lower is required amount of energy which is needed for occurring the reaction.
Temperature, pH and concentration affect the Enzyme activity. The raising of temperature generally speeds up the reaction. Due to high temperature enzyme to lose its shape and stop working. The part of enzyme where substrate bind is called the active site.
