Answer:
Step-by-step explanation:
The ΔG'° for a reaction is the standard Gibbs free energy change and represents the energy change under standard conditions (pH 7, temperature 25°C, 1 M concentrations of reactants). However, living cells often operate under non-standard conditions, such as different pH levels and reactant concentrations.
To determine if a reaction can proceed in a living cell under non-standard conditions, we need to use the ΔG formula:
ΔG = ΔG'° + RT * ln(Q)
where ΔG is the actual Gibbs free energy change, ΔG'° is the standard Gibbs free energy change, R is the gas constant (8.314 J/(mol*K)), T is the temperature in Kelvin, and Q is the reaction quotient.
In this case, the reaction is:
L-Malate + NAD+ → oxaloacetate + NADH + H+
To determine the circumstances under which this reaction can proceed, we need to calculate the ΔG value under non-standard conditions.
Quantitative analysis requires specific values for temperature, pH, and concentrations of reactants and products. Without these values, we cannot provide a quantitative analysis of the circumstances under which this reaction can proceed in a living cell.
