WebChloroplasts are enclosed by a double membrane envelope (Fig. 2.16). The space between the outer and inner membranes is called inter-membrane space. Light microscope shows the chloroplast to be composed of two parts: grana (small granules) and amorphous stroma in which grana is suspended. WebChloroplasts are endosymbiotic organelles derived from cyanobacteria. They have a double envelope membrane, including the outer envelope and the inner envelope. A complex membrane system, thylakoids, exists inside the chloroplast. It is the site of the light-dependent reactions of photosynthesis. The stroma is the main site of the carbon fixation …
Web16 hours ago · In particular, Linderstrom Lang (1952) first proposed a four-level hierarchy of protein structures: central, secondary, tertiary, and quaternary. The primary structure of the protein is the basic level of the hierarchy, which is a well-defined linear sequence of the amino acids that make up the polypeptide chain.
