Explain the following: You add 100 mL of water to a 500-mL round-bottomed flask and heat the water until it is boiling. You remove the heat and stopper the flask, and the boiling stops. You then run cool water over the neck of the flask, and the boiling begins again. It seems as though you are boiling water by cooling it.
Enzymes • Enzymes are an example of globular proteins • They are biological catalysts that speed up reactions by lowering the activation energy • They are able to work under mild conditions of temperature and pH (~7) • They do not just randomly bind to things-‐ they’re very specific • They can be regulated by being turned on or off or turned up or down Enzymes DO NOT make things occur that weren’t going to happen anyway!
