For the following reaction, ΔG^0' = +29.7 kJ/mol l-Malate + NAD+ → oxaloacetate + NADH + H⁺ Which of the following correctly describes the characteristics of the reaction as written? A) can never occur in a cell B) can occur in a cell only if it is coupled to another reaction for which ΔG^0' is positive C) can occur only in a cell in which NADH is converted to NAD+ by electron transport D) cannot occur because of its large activation energy E) may occur in cells at some concentrations of substrate and product

Question

Quizplus · Accepted Answer

The reaction can occur in cells if the concentrations of substrates and products are such that the actual Gibbs free energy change (ΔG) becomes negative, even if ΔG°' is positive.

For the Following Reaction, ΔG0' = +29

For the Following Reaction, ΔG^0' = +29
