Does ATP formation happen in the stroma or thylakoid space?
ATP formation happens in the stroma of the chloroplast during the light-independent reactions of photosynthesis, specifically in the process of ATP synthesis through the enzyme ATP synthase. In the thylakoid space, ATP is mainly produced during the light-dependent reactions of photosynthesis through the process of photophosphorylation.
Where are parts of the chloroplast ATP synthase located that are involved in the phosphorylation of ADP to ATP?
The parts of the chloroplast ATP synthase involved in the phosphorylation of ADP to ATP are located in the F1 complex, particularly on the beta subunits. These subunits contain catalytic sites that bind ADP and inorganic phosphate to facilitate ATP synthesis through a series of conformational changes and proton flow driven by the proton gradient across the thylakoid membrane.
What is function and structure of stroma?
The stroma of a plant is the region outside of the thylakoid space. This serves two functions in the both the light-dependent and light-independent (Calvin cycle) reactions. In the light-dependent reactions, the H+ ions that build up within the thylakoid begin to form a concentration gradient between the thylakoid and the stroma. As a result, the H+ ions need to diffuse into the stroma. In order to do this, the ions must travel through an enzyme known as ATP synthase. Once it does, the movement of H+ ions through ATP synthase into the stroma provides energy for ADP to become ATP. The ATP formed is an energy source to power the Calvin cycle. Now, the light-independent (Calvin cycle) reactions occur in the stroma.
Does granum or stroma contain pigments?
Granum contains pigments, specifically chlorophyll molecules, which are responsible for capturing light energy for photosynthesis. The stroma does not contain pigments but does play a role in the Calvin cycle, where carbon dioxide is converted into sugars using the energy captured by the pigments in the grana.
Where is Calvin cycle occurring?
The Calvin cycle occurs in the stroma of the chloroplasts in plant cells. It is the second stage of photosynthesis, where carbon dioxide is converted into sugars using ATP and NADPH produced during the light-dependent reactions.
Do Chloroplasts contain Stroma?
yes
Where else in chloroplasts does chemiosmosis translocates protons from?
Protons are translocated from the stroma to the thylakoid lumen in chloroplasts during chemiosmosis. This creates a proton gradient that is used by ATP synthase to generate ATP through the process of photophosphorylation.
The movement of h plus plus from the thylokoids space across the membrane and into the stroma causes what to spin and produce ATP?
ATP Synthase
What requires carbon dioxide rubp ATP and nadph?
Light independent reaction, which occurs in the stroma.
What is produced by reactions that take place in the thylakoids and are consumed by reactions in the stroma?
ATP and NADPH are produced by reactions in the thylakoids and are consumed by reactions in the stroma. The reason is because the reaction that takes place in the thylakoid is the light reaction and the one that takes place in the stroma is the light-independent reaction.
Which is the cell organelle in which 'stroma' is present?
Chloroplasts are the cell organelles that contain stroma. Stroma is the fluid-filled region within the chloroplast where the Calvin cycle takes place, which is crucial for photosynthesis.
Where are the catalytic knobs of ATP synthase located?
The catalytic knobs of ATP synthase would be located on the stromal side of the membrane. Protons travel through ATP synthase from the thylakoid space to the stroma.
What are the components of a chloroplast?
Chloroplasts consist of a double membrane, thylakoid membranes arranged in stacks called grana, stroma (fluid inside the chloroplast), and contain their own genetic material in the form of circular DNA.
Does the formation of ATP take place in the stroma?
Im in Ap Biology and it takes place in Photosystem II
Thylakoid are membrane sacs that contain?
stroma
Are grana the site of ATP production within chloroplast?
No, grana are not the site of ATP production within a chloroplast. ATP is primarily produced in the stroma of the chloroplast through the process of photosynthesis. Grana, on the other hand, contain chlorophyll pigments and are responsible for capturing light energy used in the conversion of light energy into chemical energy.
Does ATP formation happen in the stroma or thylakoid space?
ATP formation happens in the stroma of the chloroplast during the light-independent reactions of photosynthesis, specifically in the process of ATP synthesis through the enzyme ATP synthase. In the thylakoid space, ATP is mainly produced during the light-dependent reactions of photosynthesis through the process of photophosphorylation.
