Module 3 Session 1 – Readiness Assurance Test 1 Name________________________________ Team#______ (Use Scantron for iRAT and scratch-off for tRAT) 1. Living cells unavoidably convert more usable forms of energy to heat in the process of carrying out chemical reactions. This is a consequence of a. the second law of thermodynamics which states that every energy transfer or transformation increases the entropy of the universe. b. the first law of thermodynamics which states that energy cannot be created or destroyed. c. the third law of thermodynamics which states that the entropy of a perfect crystal approaches zero as the absolute temperature approaches zero. d. none of the above laws of thermodynamics. 2. The breakup of a molecule like starch into its individual glucose monomers is an example of: a. A catabolic reaction that consumes energy by building complex molecules. b. An anabolic reaction that releases energy by breaking down complex molecules. c. An anabolic reaction that consumes energy by building complex molecules. d. A catabolic reaction that releases energy by breaking down complex molecules. 3. Enzymes increase the rate of reactions by a. increasing the release of free energy. b. making the reaction independent of substrate concentrations. c. reducing the rate of reverse reactions d. lowering the activation energy barrier. 4.

Which of the following is NOT true regarding the hydrolysis reaction of ATP to ADP + Pi in the cellular environment: a. b. c. d. it is considered exergonic because it releases energy it is considered endergonic because it requires energy it will have a negative free energy change (delta G) the energy of the products will be lower than the energy of the reactants.
