Which of the following is a result of living cells not being at equilibrium?

Question

Quizplus · Accepted Answer

Living cells are constantly performing metabolic reactions that are far from equilibrium. This means that the concentrations of reactants and products are not equal, and as a result, the direction of most reactions depends on the concentration gradient. Reactions in cells must be carefully regulated in order to maintain homeostasis and prevent the cell from reaching a state of equilibrium. Therefore, option E, which states that the direction in which most reactions will proceed depends upon concentrations of reactants and products, is the correct answer. Option A is incorrect because the ΔG for a reaction can be positive or negative regardless of whether the system is at equilibrium. Option B is incorrect because many reactions can proceed in either direction depending on the concentration gradient. Option C is incorrect because the concentration gradient will determine the direction in which a reaction proceeds, even if the products are initially more concentrated than the reactants. Option D is incorrect because the entropy of cells can either increase or decrease, depending on the reaction being carried out.
