This type of wave is a transverse<span> wave. </span>Transverse<span> waves are always characterized by particle motion being perpendicular to wave motion.</span>
<span>Enzymes are catalysts in chemical reactions. What this means is that they speed up chemical reactions, which in turn means that all the actions necessary for our metabolisms occur as a result of catalysts. This goes from fighting illnesses and diseases to dissolving food. We couldn't live without them because our metabolisms would be so slow that we would die as nothing could work.</span>
