UCI Bio 93 Midterm 2 Questions and Answers Rated A+ What is a metabolic pathway? A pathway that a molecule goes through, resulting in a specific product. What is metabolism? The totality of an organisms chemical reactions Gibbs free energy Portion of a system that can perform work when temp and pressure are uniform throughout the system. What is a way to show change in free energy? What does a negative Delta G mean? A process that is spontaneous What does spontaneous mean...

You are studying two reactions. The only difference in these reactions is that one has an enzyme and the other does not. Which of following statements must be false? A. The enzymatic reaction has less activation energy because it does not have a transition state. B. The activation energy of the reaction that lacks an enzyme is greater than the reaction that has an enzyme. C. The rate of reaction is greater in the enzymatic reaction. D. The delta G and the entropy of both of the reactions a...

activation energy correct answers energy needed to get a reaction started Delta G (change in G - change in free energy) correct answers respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme correct answers catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition correct answers results in decrease in act...

adenosine triphosphate (ATP) - energy currency of life, high energy molecule that stores energy we need to do anything. Universal unit of energy exhange NAD+, nicotinamide adenine dinucleotide - coenzyme in all living cells. Required for fundamental biological processes. Oxidized form active transport - requres energy. molecules move against concentration gradient. Ex. protein channels, endocytosis, exocytosis. Can be coupled to exergonic chemical reactions or exergonic movement of molecul...

A dynamic steady state results when A. a molecule stops being degraded. B. an organism is at equilibrium with its surroundings. C. there is no net energy transfer. D. the rate of intake or synthesis of a molecule equals the rate of its disappearance - Choice D is correct. A dynamic steady state results when the rate of synthesis or intake of a molecule equals the rate of its breakdown, consumption, or conversion into some other product. For example, a dynamic steady state in the blood ma...
