Four environmental factors of enzymes were tested in lab. The changing of pH‚ substrate concentrations‚ temperature‚ and an inhibitor (NaCl) and the effects it hade on the enzyme turnip peroxidase. Enzymes are biological catalysts which increase reaction rates by lowering the activation energies of substrates. A substrate is a reactant that interacts with the enzyme. The enzyme and substrate can be viewed as the recently discovered "induced fit model"‚ which suggests enzymes are flexible and dynamic
