- Which one of the following statements is completely TRUE? O When AG > 0, the reaction is BOTH product-favored (spontaneous) AND endergonic. When AG 0, the reaction is BOTH reactant-favored (nonspontaneous) AND endergonic. When AG > 0, the reaction is BOTH product-favored (spontaneous) AND exergonic. When AG > 0, the reaction is BOTH reactant-favored (nonspontaneous) AND exergonic. When AG < 0, the reaction is BOTH reactant-favored (nonspontaneous) AND exergonic.arrow_forwardOn the free energy diagram shown, label the intermediate (s) and transition state(s). Is the reaction thermodynamically favorable? Reaction.arrow_forwardT/F A catalyst changes only the rate at which equilibrium is achieved; it has no effect on the position of the equilibrium. This means that a catalyst can enhance the rate of exergonic reactions but cannot somehow change the ΔG′ to allow an endergonic reaction to become spontaneousarrow_forward
- this one represents an endothermic reaction. Things are similar: the flat line on the left (beginning of the reaction) is the total energy possessed by the reactant molecules; once again, kJ stands for energy in kiloJoules, thousands of Joules. The flat line on the right (reaction complete) is the total energy of the products. Since an endothermic reaction has a net absorption of energy (taking this extra energy from the surroundings), the products have higher energy than the reactants. Question: the energy of the reactant molecules is kJ. [to answer, simply identify the correct y-axis coordinate.] 250 200 PE (kJ) 150 100 50 Reaction pathwayarrow_forwardDetermine the direction that each of the reactions will progress. Assume that the reactants and products are present in equimolar amounts. The standard free energy of hydrolysis of ATP is - 30.5 kJ/mol. fructose + ATP fructose 6-phosphate + ADP The standard free energy of hydrolysis for fructose 6-phosphate is -15.9 kJ/mol. 3-phosphoglycerate + ATP 1,3-bisphosphoglycerate + ADP The standard free energy of hydrolysis for 1,3-bisphosphoglycerate is -49.3 kJ/mol. creatine + ATP creatine phosphate + ADP The standard free energy of hydrolysis for creatine phosphate is -43.0 kJ/mol.arrow_forwardThe following questions are based on the reaction A+ B ↔ C+D shown in Figure 8.1. 1.

Which of the following in Figure 8.1 remains unchanged by having an enzyme included? a) b b) d c) a d) c 3.

- if the reaction given below occurs and pure A and B were mixed, which of the following would take place as equilibrium was established A + B ⇌ C a. the concentration of C would increase for a time, then remain constant b. the concentration of A would increase for a time, then decrease c. the concentration of B would increase for a time, then remain constantarrow_forwarduce the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions The reverse of this reaction is always spontaneous but proceeds slower at temperatures below 132. °C. AH is (pick one) AS is (pick one) His (pick one) B This reaction is endothermic. AS is (pick one) This reaction is spontaneous except below 110. °C but proceeds at a slower rate below 135. °C. AH IS (pick one) AS is (pick one)varrow_forwardWhich of the following statements are true for BOTH the "transition state" and an "intermediate" of reaction? (This is a multi-select question, select all that apply.). Both are only observed in enzyme-catalyzed reactions. Both can be converted to product(s) or might decompose back to the reactant(s). Neither are part of the "net equation" for the reaction. Both contain covalent bonds are in the process of breaking and/or forming. Both are part of every chemical reaction. (i.e. the mechanisms of all chemical reactions, whether enzyme catalyzed or not, will have involve both a transition state and an intermediate).arrow_forward
- Consider the analogy of the jiggling box containing coins that was described on page 85. The reaction, the flipping of coins that either face heads up (h) or tails up (T), is described by the equation h ↔ T, where the rate of the forward reaction equals the rate of the reverse reaction.a. What are ΔG and ΔG° in this analogy? b. What corresponds to the temperature at which the reaction proceeds? What corresponds to the activation energy of the reaction? assume you have an “enzyme,” called jigglase, which catalyzes this reaction. What would the effect of jigglase be and what, mechanically, might jigglase do in this analogy?arrow_forward(please type answer no write by hend)arrow_forwardWhich of the following aspects of catalysis by enzymes can NOT be explained by the Fischer Lock and Key Hypothesis? Enzymes will lower the activation energy barrier for reaction. Enzymes will specifically recognize their substrates. Appropriate substrates will bind to the enzyme to form a Michaelis complex. Enzymes have an "active site" where appropriate substrates will be bound. Two of the above cannot be explained by the Fischer "Lock and Key" Hypothesis.arrow_forward
