Compartmentation of cells
WebApr 1, 2001 · Abstract. Critical to defining photosynthesis in C 4 plants is understanding the intercellular and intracellular compartmentation of enzymes between mesophyll and bundle sheath cells in the leaf. This includes enzymes of the C 4 cycle (including three subtypes), the C 3 pathway and photorespiration. The current state of knowledge of this … WebMetabolic compartmentation of amino acid metabolism in brain is exemplified by the differential synthesis of glutamate and glutamine from the identical precursor and by the localization of the enzyme glutamine synthetase in glial cells. In the current study, we determined if the oxidative metabolism …
