The rate of photosynthesis and the initial rate of accumulation of inorganic carbon within the spheroplasts were very close to those observed in intact cells. The steady-state intracellular inorganic carbon pool, however, was smaller in spheroplasts than in intact cells. It is suggested that the cell wall does not play an essential role in the process of HCO3 − transport (leading to accumulation of inorganic carbon internally) but may have a significant impact on the diffusional dissipation of the intracellular pool of inorganic carbon.", }
