Enzyme
a. Write one or two sentences explaining how enzymes work, using vocabulary words from the diagram.

Consider a chemical reaction where a molecule A bonds with a molecule B to create a molecule A-B (A stuck to B). Under a given set of conditions --- the temperature the reaction occurs at, the pressure of the atmosphere, and the concentrations of the reactants A and B and the product A-B --- this reaction happens at a certain speed. For example, 3 A molecules and 3 B molecules become 3 A-B molecules each second.
