Jane b. reece, lisa a. urry, michael l. cain, steven a. wasserman, peter v. minorsky, robert b. jackson. How do we produce the required amount of atp? oxidation of glucose to co2. Reactions are part of a complex network of chemical reactions: metabolism. These reactions must obey the laws of thermodynamics energy cannot be created or destroyed entropy (disorder) is only increasing. Definitions: metabolism - the totality of an organism"s chemical reactions, catabolic - release energy by breaking down complex molecules into simpler compounds, anabolic- consume energy to build complex molecules from simpler ones. Reaction 3: each step is catalyzed by a specific enzyme. The laws of energy transformation: thermodynamics - study of energy transformations, -closed system-liquid in a thermos- is isolated from its surroundings, -open system- energy and matter can be transferred between the system and its surroundings. Thermodynamics first law of thermodynamics: the energy of the universe is constant:
