Enzymes

• Active sites have specific shapes to fit their corresponding substrates.
• Non-competitive enzyme inhibition occurs when the inhibitor binds to an allosteric site on the enzyme, changing its shape and preventing substrate from binding to the active site.
• Competitive enzyme inhibition occurs when the inhibitor competes with substrate for binding to the active site, reducing the rate of reaction.
• Enzyme inhibitors can be competitive or non-competitive.
• Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms.
• Allosteric regulation involves changing the shape or conformation of the enzyme through interactions between different parts of the molecule.
