ARNON Table IV shows that, at the high Hght intensity at which cycHc photo- phosphorylation by purified grana was measured, the highest rates were obtained in the system catalyzed by phenazine methosulphate. Photo- phosphorylation in this system was not increased by the addition of an aqueous chloroplast extract. In contrast, photophosphorylation catalyzed. Fig. II.

The pyrenoid is associated with starch and/or protein synthesis and/or storage, (b) A corn chloroplast. Sketch of an electron micrograph of a chloroplast from Zea mais. The dark regions are the grana. They are cylinders about 4,000 to 6,000 A in diameter and 5,000 to 8,000 A in height. After E. I.
