Explain why enzymes are involved in exergonic reactions, such as lactose breaking down into glucose and galactose, and whether these reactions can occur spontaneously
What will be an ideal response?
Although these reactions are exergonic and therefore could occur spontaneously, they would take a very long time to occur. Enzymes accelerate the rates of these reactions.
