Introduction Catalysts help speed up reactions. Catalysts come from a certain molecular substance found in cells. These are called enzymes. Enzymes would temporarily bond to one or more reactants of a reaction and catalyze, meaning they speed up the process with lower activation energy needed. Enzymes provide a variety of functions such as cells using an enzyme to rid themselves of a poisonous substance (hydrogen peroxide) and also energy usage. catalase 2H2O(l) ( 2H2O(l)

Chapter 4 * Figure 4-2 * Modification of a germ cell to form a mammalian sperm. (A) The centriole produces a long flagellum at what will be the posterior end of the sperm, and the golgi apparatus forms the acrosomal vesicle at the future anterior end. The mitochondria collect around the flagellum near the base of the haploid nucleus and become incorporated into the midpiece ("neck") of the sperm. The remaining cytoplasm is jettisoned and the nucleus condenses. The
