The enzyme ribose‑5‑phosphate isomerase catalyzes the conversion between ribose‑5‑phosphate (R5P) and ribulose‑5‑phosphate (Ru5P) through an enediolate intermediate. In the Calvin cycle, Ru5P is used to replenish ribulose‑1,5‑bisphosphate, a substrate for rubisco. For the conversion of R5P to Ru5P, if Δ G ° ′ = 0.460 kJ / mol ΔG°′=0.460 kJ/mol and Δ G = 3.30 kJ / mol ΔG=3.30 kJ/mol , calculate the ratio of Ru5P to R5P at 298 K 298 K . [ Ru 5 P ] [ R 5 P ] = [Ru5P][R5P]= Which of the statements is true? This reaction is favorable, and it is not likely regulated. This reaction is favorable, and it is likely regulated. This reaction is not favorable, and it is not likely regulated. This reaction is not favorable, and it is likely regulated.
