The stack of thylakoids
WebAbstract. Chloroplasts contain a system of membrane sacs, the thylakoids, some of which are stacked to form grana (singular, granum), whereas others float freely in the stroma. It is on the thylakoid membranes that the electron carriers necessary for photosynthesis reside. There has been continuous speculation and discussion about the function ... WebWhich statement about thylakoids in eukaryotes is not correct? Thylakoids are assembled into stacks. Thylakoids exist as a maze of folded membranes. The space surrounding thylakoids is called stroma. Thylakoids contain chlorophyll. 4. From where does a heterotroph directly obtain its energy?

WebThese thylakoids form stacks of around 15 or more disks. A stack of thylakoids is a granum, the plural of which is grana. These grana are interconnected by thin membranous folds called lamellae, which help increase the available surface area to capture light energy. Within each thylakoid is an aqueous space called the lumen. WebSolar energy splits two molecules of H 2 O into molecular oxygen (O 2 ), four protons (H + ), and four electrons. …to hollow sacklike disks called thylakoids.

WebAbstract. Thylakoids of land plants have a bipartite structure, consisting of cylindrical grana stacks, made of membranous discs piled one on top of the other, and stroma lamellae which are helically wound around the cylinders. Protein complexes predominantly located in the stroma lamellae and grana end membranes are either bulky [photosystem I ...
