Globe is more accurate than maps as it shows, accurate distance, directions, shape
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. ... The binding of a substrate to an enzyme active site is termed the "enzyme-substrate complex.
