define metabolism and the fundamental differences between anabolism and catabolism
Define metabolism, and describe the fundamental differences between anabolism and catabolism. p. 112 metabolism- refer to the sum of all chemical reactions within a living organism. catabolism- (energy releasing) the breakdown of complex organic compounds into simpler ones; hydrolytic reactions and exergonic (produce more energy than consumed) anabolism- (energy requiring) the building of complex organic molecules from simpler ones; involve dehydration synthesis reactions and they are endergonic (consume more energy then they produce) Identify the role of ATP as an intermediate between catabolism and anabolism. p. 112 catabolic reactions provide building blocks for anabolic reactions and furnish the energy need to drive anabolic reactions. this coupling of energy-requiring and energy-releasing reactions is made possible through the molecule ATP.
