1. What is an enzyme?
Enzymes are catalyst proteins that help speed up chemical reactions in cells and can be reused.
2. How do enzymes work?
Enzymes are selective catalysts that require a specific shape in order for the chemical reaction to work. Enzymes can break down large molecules, and can also help produce a new molecule from two substrates. Enzymes produce and break down molecules two ways. The lock and key method, a perfect fit for each substrate, and the induced fit method is the other way enzymes work, the substrates don't fit perfectly, so they alter their shape to form a perfect match.
3. What factors inhibit enzyme action?
Some factors that inhibit enzymes are pH, temperature, enzyme concentration, and substrate concentration. The higher the temperature, the faster the reaction time, the lower the temperature, the reaction time slows. The pH in an enzyme can also effect reaction time, for each enzyme it can vary, but the best pH concentration is where the enzyme is most active is called the optimum pH. Enzyme and substrate concentration effect each other and can speed up or slow down reaction times.
