For the reaction B A at standard conditions with [B] =1 M and [A] =1 M, AG is initially a large negative number. As the reaction proceeds, [B] decreases and [A] increases until the system reaches equilibrium. How do the values of AG and AG" change as the reaction moves toward equilibrium? both AG and AG stay the same O AG reaches zero and AG" becomes more negative AG becomes less negative and AG" stays the same AG stays the same and AG becomes less negative AG becomes positive and AG" becomes positive
Calculate theequilibrium constant and thefree energy of (Mg)ATP hydrolysis in a closed system in which concentrations of ATP, ADP and Piare, respectively, 3.5, 1.0, and 5 mMand 25 degrees Celsius. Is the reaction spontaneous?R = 8.314 J/(deg Kelvin-mol).

(please type answer fast).
1) Define metabolism and describe the importance of metabolism to life. 2) Calculate the change in free energy (∆G ) for the below reaction and answer the two follow up questions: Gfinal state = 3.4 kcal/ mol and Ginitial state = 10.7 kcal/ mol Recall: ∆G = Gfinal state – Ginitial state a. Is this a spontaneous or non-spontaneous reaction? Explain. b. Is there energy released from this reaction which can be used to do work? Explain. 2) List four conditions which impact an enzymes rate of activity. Explain.
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.
Time Mg (s) + 2 HCI (aq) + MgCl, (ag) + H, (g) The reaction between solid magnesium and hydrochloric acid is represented by the equation. A student combines 0.1 mol of Mg (s) with 0.2 mol of HCI (ag) and monitors the amount of Mg (s) as the reaction proceeds. The student conducts the experiment once with a single chunk of Mg (s) and once with Mg (s) pellets. Assuming that the mass of Mg (s) is plotted for both experiments, which curve represents the mass of Mg (s) for the experiment that uses Mg (s) pellets? Curve A, because the reaction rate is faster when the surface area increases. B Curve B, because the reaction rate is slower when the surface area decreases. Curve C, because the reaction rate is slower when the surface area decreases. D Curve D, because the reaction rate is faster when the surface area increases.
Answer for the number 7 question, Thank you. No need for long explanation.
ANSWER A AND B PLS
Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d. The change in free energy for the reaction is greater in the catalyzed reaction, compared to the uncatalyzed reaction e. The enzyme stabilizes the transition state for the reaction Released Energy pes
