: Based on analysis of a hexokinase from spinach localized on the outer envelope membrane of the chloroplast, it is hypothesized that the Glucose transported out of the chloroplast through this transport reaction is immediately phosphorylated to produce glucose-6-phosphate. This compound cannot passively diffuse or be re-imported back into the chloroplasts, thus a concentration gradient can be established to promote the transport of Glucose out of the stroma and into the cytoplasm [10561488].natural substrates
