A) Which of the following statements is FALSE? a. Energy can be transferred between a system and the surroundings b. Organisms are open systems as they can create energy from their environments c. In an open system energy, can be converted from one form into another d. Organisms are open systems as they can exchange both energy and materials with their environments B) A biochemical reaction will proceed in the direction as written (forward) if 1. AG zero 2. AG >0 3. AG 0 4. AH >0 C) The AG of a reaction: 1. will not change if the temperature of the reaction is changed 2. can be used to calculate whether a reaction is thermodynamically favorable under defined non-standard conditions 3. will change if the concentration of reactants and products are changed. 4. is not related to the equilibrium constant. D) Calculate the AG for the reaction: fructose-6-phosphate- glucose-6-phosphate (Given the equilibrium constant is 1.97 and the physiological relevant temperature is 37 C) i. 2.56 kJ/mol ii. -2.56 kJ/mol iii. 1.75 J/mol iv. 1.75 kJ/mol E) A thermodynamically unfavorable reaction can become favorable when coupled to a highly endergonic reaction i. True ii. False F) System does 435 kl of work (w), and loses 312 kJ of heat (q) to the surroundings. What is the change in internal every of the system? i. 747 kJ ii. -465 kJ iii. 747 kJ iv. 465 kJ
