structure of enzymes - tertiary globular proteins, all enzymes are... - biological catalysts, catabolic reactions - larger molecules broken down into smaller molecules, anabolic reactions - smaller molecules built up into larger molecules, lock and key theory - The active site of an enzyme is structured to fit a specific substrate, induced fit theory - the binding of a substrate to the active site causes it to change shape to enhance activity, activation energy - energy needed to break chemical bonds inside of molecules, temperature or pH too high - enzyme will denature, optimum - best condition for enzyme to work in, two types of inhibitors - competitive and non competitive , competitive inhibitors - has a similar shape to substrate and blocks it from binding to the active site , non-competitive inhibitors - binds to a different part of the enzyme which changed shape of active site ,
