1. Metabolism is efficient Capturing energy from glucose may include 25 different chemical reactions Each reaction controlled by a separate enzyme Glucose is converted to many short-lived metabolic intermediates before it  Step-wise reactions allow capture of energy efficiently Captured energy can be used other places in the cell efficient Cellular metabolism (catabolic or anabolic reactions) follows metabolic  pathways - sequences of enzyme-controlled chemical reactions - end product of one reaction serves as reactant in next reaction 2. Metabolism is efficient Enzyme only binds to specific type of molecule (substrate) Enzymes only lower energy of activation for molecules to which they bind Metabolic pathways have many enzymes, each of which catalyzes only one
