Suppose you discovered a mutant strain of spinach in which the thylakoid membranes were slightly permeable to protons, thus allowing a slow leakage (remember that normal membranes are not permeable to protons at all). What change in the reactions of photosynthesis might occur in compensation for this defect? A)Cyclic electron transport would increase. B)Noncyclic electron transport would increase. C)O₂ production would decrease. D)Cyclic electron transport would decrease. E)Noncyclic electron transport would decrease.
