Questions

  1. 1.

    Which of the following statements correctly characterizes an exergonic reaction in cellular metabolism?

    • A) It requires a continuous net input of free energy to proceed, resulting in a positive change in free energy (ΔG>0\Delta G > 0).
    • B) It shifts the system away from chemical equilibrium and increases the total free energy stored within the products.
    • C) It occurs spontaneously and releases free energy, resulting in a negative change in free energy (ΔG<0\Delta G < 0).
    • D) It decreases the entropy of the universe and absorbs thermal energy from the surrounding cellular environment.
