What is a thylakoid and what does it do?
Thylakoids are the internal membranes of chloroplasts and cyanobacteria, and provide the platform for the light reactions of photosynthesis.
What does a thylakoid do during photosynthesis?
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria. It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
What is inside of thylakoid?
The interior contains flattened sacs of photosynthetic membranes (thylakoids) formed by the invagination and fusion of the inner membrane. Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll).
What is the inside of a thylakoid called?
The space inside the thylakoid membranes is called the thylakoid space. Each stack of thylakoids is called a granum (plural = grana). The fluid enclosed by the inner membrane that surrounds the grana is called the stroma.
What do thylakoids contain?
Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The grana are connected to other stacks by simple membranes (lamellae) within the stroma, the fluid proteinaceous portion containing the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.
What does the thylakoid contain?
What is the process that occurs in the thylakoid?
Reactions performed in the thylakoid include water photolysis, the electron transport chain, and ATP synthesis. Photosynthetic pigments (e.g., chlorophyll) are embedded into the thylakoid membrane, making it the site of the light-dependent reactions in photosynthesis.
What does a thylakoid does during photosynthesis?
A thylakoid is a sheet-like membrane-bound structure that is the site of the light-dependent photosynthesis reactions in chloroplasts and cyanobacteria . It is the site that contains the chlorophyll used to absorb light and use it for biochemical reactions.
What goes in the thylakoid?
Thylakoids are usually arranged in stacks (grana) and contain the photosynthetic pigment (chlorophyll). The grana are connected to other stacks by simple membranes (lamellae) within the stroma, the fluid proteinaceous portion containing the enzymes essential for the photosynthetic dark reaction, or Calvin cycle.
What does the thylakoid membrane contain?
Thylakoid membranes contain integral membrane proteins which play an important role in light-harvesting and the light-dependent reactions of photosynthesis. There are four major protein complexes in the thylakoid membrane:
