This document defines energy and different types of energy like potential and kinetic energy. It also defines metabolism, listing the two main types and defines enzymes, naming the most important classes. It asks to name the three metabolic pathways and defines aerobic cellular respiration and anaerobic respiration. It defines fermentation and asks to name the final products of anaerobic respiration. It asks about the main function of enzymes, names the six types of enzymes and defines energy of activation. It asks about factors that affect enzyme activity and defines what a cofactor is.
