1. Which of the following is FALSE with respect to coupledreactions? they occur in ALL cells (bacteria, plants, animals, etc.) enzymes are typically involved endergonic reactions power exergonic reactions the coupled reaction has a ?G value that is negative none of the above (i.e., all of the above are TRUE)
2. Which of the following reactions is LEAST likely to bespontaneous? One with a: very large increase in entropy and a very large decrease inenthalpy very large increase in entropy and a very small increase inenthalpy very small decrease in entropy and a very large decrease inenthalpy very small increase in entropy and a very small decrease inenthalpy very small decrease in entropy and a very small increase inenthalpy
3. Energy of activation refers to the: A) ?G of a reaction B) difference in energy between the transition state and theproduct C) difference in energy between substrate and product D) net change in free energy E) energy input needed to reach the transition state
4. Homeostasis refers to maintaining a relatively constantenvironment, and is achieved to a large extent by how enzymes areregulated. For example, when the end product of a pathway regulatesan enzyme that acts early in the same pathway, the effect is mostoften: stimulation if an anabolic pathway, and inhibition if acatabolic pathway inhibition if an anabolic pathway, and stimulation if acatabolic pathway stimulation, whether an anabolic or catabolic pathway inhibition, whether an anabolic or catabolic pathway
5. Enzymes function by: decreasing the free energy level of the reactants decreasing the free energy level of the transition state increasing the free energy level of the reactants changing delta G from positive to negative changing delta G from negative to positive increasing the free energy level of the products decreasing the free energy level of the products
