Solution 2
The correct answer is: "Enzymes increase the rate of reaction without being used up. This is achieved by the binding of substrate to the enzyme active site, where the reaction is catalysed."
Enzymes are biological catalysts that speed up chemical reactions in cells. They do this by lowering the activation energy of the reaction, which is the energy required to start a reaction. The enzyme binds to the substrate (the molecule that the enzyme will act upon) at its active site, forming an enzyme-substrate complex. This binding induces a change in the enzyme's shape, which allows it to catalyze the reaction. After the reaction is complete, the enzyme releases the product and is free to bind to another substrate. Because the enzyme is not consumed in the reaction, it can catalyze many reactions in a short amount of time, greatly increasing the rate of the reaction.
