Enzymes

• When the substrate enters the active site, it undergoes chemical changes to form products.
• The active site on the enzyme has a specific shape that fits only one type of molecule, called the substrate.
• Enzyme-substrate complex is formed when the substrate binds to an enzyme.
• Product release occurs when the bond between the enzyme and the product breaks.
• Enzymes are biological catalysts that speed up biochemical reactions without being used up or changed themselves.
• Enzymes lower the activation energy required for a reaction by providing an alternative pathway with a lower activation energy barrier.
• Catalysts are substances that increase the rate of a reaction without being used up or changed themselves.
• Enzymes are biological catalysts found inside cells.
• Activation energy is the minimum amount of energy needed for a reactant to overcome its repulsion and initiate a chemical reaction.
• Denaturation can occur due to changes in temperature, pH, or other environmental conditions.
• The lock-and-key model suggests that enzymes have specific active sites where substrates fit like keys into locks, allowing them to be converted into products.
