BIO 311C Chapter Notes - Chapter 8: Non-Competitive Inhibition, Activation Energy, Pepsin
Document Summary
Introduction to metabolism: define metabolism, anabolism, and catabolism and give examples for each. Metabolism : sum of all biochemical reactions that take place in an organism. * breaking down glucose: describe how the two laws of thermodynamics apply to biological systems. First law : total energy is constant; energy can only be transferred. Second law : energy transfer leads to increased entropy (disorder) * biological systems are open systems while the universe is a closed system. * spontaneity of reaction determines if it will occur: define entropy, enthalpy and free energy and give examples. understand how they are related to each other in the free energy reaction. Enthalpy : heat content or total potential energy. Free energy : portion of a system"s energy that is available to perform work. *endergonic (+ g) and exergonic (- g: know examples of exergonic, endergonic, exothermic and endothermic reactions and combinations of the same. Endergonic (+ g) : cooling water at room temperature.
