What is the role of enzymes in biological reactions?

Enzymes play a crucial role in facilitating biochemical reactions by acting as catalysts. They speed up the rate of these reactions by lowering the activation energy required for the reaction to occur. This allows biological processes to happen at a faster pace and under milder conditions than would be possible without these enzymes. This is particularly important in living organisms, where efficient reaction rates are necessary for sustaining life.

Enzymes are highly specific, meaning each enzyme typically catalyzes a particular reaction or type of reaction. This specificity and efficiency ensure that metabolic processes occur in a controlled and timely manner, making enzymes essential for maintaining the various functions necessary for life.
