PSII antenna size was drastically reduced in the margins of the grana stack and stroma lamellae fractions as compared to the grana. Thus, primarily the key difference between thylakoid and stroma is that the thylakloid is a membrane-bound compartment situated in the chloroplast whereas the stroma is the … 2. B) space between the inner and outer membranes of a mitochondrion. Prolamellar bodies and grana have nearly the same amount of total lipid and total carotenoid per mg of protein although their respective compositions differ. An aqueous compartment which starch granules are usually found. The ~ are flattened disks, bounded by a membrane with a lumen or thylakoid space within it. Stroma: The stroma refers to the fluid-filled matrix inside the inner membrane of the chloroplast. Stroma is the cytoplasm of the chloroplast which is composed of a transparent liquid, in which thylakoid (grana), sub organelles, DNA, ribosome, lipid droplets and starch grains are present.

Grana: Stacks of ~ found in the stroma of Chloroplasts where photosynthesis occurs. - fluid in the chloroplast surrounding the grana. 26 … Picosecond time-resolved fluorescence decay kinetics of PSII were characterized by three exponential decay components in the grana fractions, and were found to have only two decay components with slower lifetimes in the stroma. Stroma vs Stoma . No other organelle has all these three components. A chloroplast contains several of these structures, collectively known as grana. They are large organelles elf 4-10 micrometers, It is continuous with stacks of flattened membrane sacs which…. 28 terms. On a protein basis, the lipid, chlorophyll, and carotenoid contents are lower (2.3, 10, and 20 times, respectively) in stroma lamellae than in grana membranes, but the latter contains a higher proportion of β-carotene, … Thylakoids are membrane bound compartments or disks where the light reaction takes place. ... contai…, found in cytoplasm ... transport of lipids…, 1) Fatty acids and pyruvates enter the mitochondria ... 2) When t…, ETC will pass electrons down a series of proteins.
