| Question | Answer |
| Enzymes | Biological catalysts that Increase the rate of a reaction while decreasing the activation energy required |
| Induced Fit | Mechanism where an enzyme binds with a substrate, not exactly complementary and changes its shape to produce an exact fit |
| Extracellular Enzymes | Enzymes that work outside of the cell that affect digestive reactions |
| Activation Energy | The energy required to start a chemical reaction. Reduced by enzymes |
| Enzyme Substrate Complex | Formed when the substrate binds to the enzyme with weak chemical bonds |
| Metabolic Reactions | Reactions that are controlled by enzymes and take place within cells |
| Inactivated | The state of the enzyme when it is below its optimal temperature / below and above its optimal pH |
| Denature | When the tertiary structure of an enzyme (protein) changes therefore changing its biochemcial properties |
| Lock and Key | Mechanism used to explain the binding of enzymes where the substrate is simply drawn into the matching cleft and fits perfectly |
| Ribosomes | Sites of protein, therefore enzyme, synthesis |
| Cofactors | Inorganic chemical substances that help the enzyme increase the rate of reaction. Reusable |
| Coenzymes | Organic molecules that help the enzyme catalyse reactions. Used up in a reaction and need to be constantly replaced before another reaction can take place |
| Intracellular | Enzymes used inside the cell. Usually used in metabolism |
| Catalysts | Substances that increase the rate of reaction without being used in the process |
| Saturation | the point at which all the active sites of the enzymes are occupied as there is a surplus or high concentration of substrate |
| Vitamins | Co-enzymes as they are organic |
| Catabolic | reactions that release energy after breaking bonds in polymers or large molecules into smaller parts, sub units or monomers |
| Limiting Factor | Check: To Do |
| Feedback Inhibition | When the last product of a metabolic pathway (sequence) that becomes an inhibitor and it binds to the first enzyme of the metabolic pathway and it temporarily stops the metabolic pathway until all the final products have been used up |
| Catalytic Cycle | A reaction that involves a catalyst |
