LIFESCI 2 Study Guide - Midterm Guide: Atp Hydrolysis, Exergonic Process, Endergonic Reaction
Document Summary
Week 1: explain the first and second laws of thermodynamics. 1st: energy is neither created nor destroyed, only transferred between q & w. Endergonic requires energy, anabolic reactions: discuss how an energetically favorable reaction can be coupled to and drive a separate energetically unfavorable reaction. Coupling endergonic (non-spontaneous) reactions to exergonic (spontaneous) reactions, the released atp in the exergonic reaction is hydrolyzed to release energy and is used to fuel the endergonic reaction. Atp synthesis= non-spontaneous: explain what is meant by the term equilibrium. Forward reaction rate = reverse reaction rate. (cid:791)g=0: differentiate between anabolic and catabolic processes. Anabolic reactions build up larger molecules from smaller molecules and require atp. Catabolic reactions break down larger molecules into smaller molecules and release atp: predict the favorable direction of a reversible reaction based on the relative concentrations of products and reactants. [products] > [reactants] shift to the left, favoring reactants.
