Enzymes

• Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.
• When the substrate enters the active site, it undergoes chemical change (catalysis).
• The active site of an enzyme has a specific shape that fits only one type of molecule, called its substrate.
• Enzyme-substrate complex is formed when the substrate binds to an enzyme.
• The active site is the part of an enzyme where substrates bind to initiate a reaction.
• Enzymes lower activation energy by providing a specific environment for the reaction to occur.
• Enzymes have optimum temperatures at which they work best.
• An enzyme's activity can be affected by changes in temperature or pH level.
• If the temperature is too high, the enzyme will denature and lose its ability to function properly.
• Active sites have a unique three-dimensional structure that allows them to fit perfectly with their corresponding substrates.
