Granal thylakoids
WebThe machinery that conducts the light-driven reactions of oxygenic photosynthesis is hosted within specialized paired membranes called thylakoids. In higher plants, the thylakoids are segregated into two morphological and functional domains called grana and stroma lamellae. A large fraction of the luminal volume of the granal thylakoids is occupied by … WebJun 15, 2016 · We hypothesize possible involvement of chloroplast carbonic anhydrase in thylakoid granal structure maintenance. The structural disturbances and the inhibition of photochemical activity of chloroplasts are possible consequences of the carbonic anhydrase inactivation by SAR treatment leading to violation of HCO 3 − –CO 2 equilibrium.
