Document Summary
Pathways are catalyzed by an enzyme or ribozyme. Cells carry out 3 major types of work. Synthesis of complex biological molecules from much simpler. Energy is needed to increase the molecular complexity of a cell. Requires energy to take up nutrients, eliminate wases, and precursors. Energy required for cell motility and the movement of structure. Focuses on the energy differences between the initial state and the final state of a system. Not concerned with the rate of the process. Energy can be neither created nor destroyed. Measure of the randomness (disorder of a system) Randomness of the universe increases (the system and its. Amount of heat energy needed to raise 1 ram of water from 14. 5 to 15. 5 degrees celsius. Units of work capable of being done. Free energy change predicts the nature of chemical reaction. About the same as the change in total energy during the reaction. Delta s change in entropy occurring during the reaction.
