WebbA chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in the cells. The ATP and NADPH is … WebbAlthough parts of the pathway are now understood, other parts remain to be discovered. Glucans derived from starch granules are hydrolyzed via beta-amylase to maltose, which is exported from the chloroplast. In the cytosol maltose is the substrate for a transglucosylation reaction, producing glucose and a glucosylated acceptor molecule. Webb6 apr. 2024 · Transitory starch granules result from complex carbon turnover and display specific situations during starch synthesis and degradation.
