5D - The multitude of reactions within our cells are sped up by enzymes. Without these biomolecules, these biochemical pathways would be as slow as a turtle. For instance, without enzymes, your body may never be able to break down and absorb the hamburger you just had for lunch. The hamburger would simply sit there, a lump in your stomach, until reactions slowly started to happen on their own - enzymes speed that up!
Enzymes are often named for their reactions, and you can often discern the function of an enzyme from its name. We will learn about six types of enzymes based on the type of reaction they catalyze. By Ross Firestone.
