What else can I help you with?
Is the stroma located within the thylakoid membrane?
No, the stroma is not located within the thylakoid membrane. The stroma is the fluid-filled space outside the thylakoid membranes in the chloroplast.
Gel filled space in the chloroplast surrounding thylakoid stack?
The gel-filled space in the chloroplast surrounding the thylakoid stack is called the stroma. It plays a crucial role in the light-independent reactions of photosynthesis, where carbon dioxide is converted into glucose. The stroma also contains enzymes, DNA, and ribosomes, allowing for the synthesis of proteins and other molecules within the chloroplast.
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.
Where is the location of the dark reactions in photosynthesis?
The dark reactions of photosynthesis, also known as the Calvin cycle, take place in the stroma of the chloroplasts in plant cells. Here, carbon dioxide is fixed and converted into glucose with the help of ATP and NADPH produced during the light reactions.
Does a stroma contains a thylakoid?
a thick fluid inside chloroplasts
Is the stroma located within the thylakoid membrane?
No, the stroma is not located within the thylakoid membrane. The stroma is the fluid-filled space outside the thylakoid membranes in the chloroplast.
Is the chlorophyll located in the stroma?
No, chlorophyll is located in the thylakoid membranes within the chloroplasts, not in the stroma. The stroma is the fluid-filled space surrounding the thylakoid membranes where the Calvin cycle takes place.
Is there a relationship between the pH of the inner thylakoid space and the pH of the stroma?
yes
What are the parts of a chloroplasts?
The parts of a chloroplast are thylakoid, grana, inner membrane, outer membrane, intermembrane space, stroma, and stroma.
What are the parts of chloroplast?
The parts of a chloroplast are thylakoid, grana, inner membrane, outer membrane, intermembrane space, stroma, and stroma.

It plays a crucial role in the light-independent reactions of photosynthesis, where carbon dioxide is converted into glucose. The stroma also contains enzymes, DNA, and ribosomes, allowing for the synthesis of proteins and other molecules within the chloroplast.
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.
What are stroma and grana portions of?
The stroma and grana are portions of a chloroplast. The stroma is the fluid-filled space surrounding the thylakoid membranes where the Calvin cycle reactions occur, while the grana are stacks of thylakoid membranes where light-dependent reactions take place through the presence of chlorophyll.
What is the fluid region of the chloroplast?
The fluid region of the chloroplast is known as the stroma. It is a semi-liquid substance that fills the space between the thylakoid membranes and surrounds the thylakoid stacks called grana. The stroma contains enzymes and other molecules that are involved in the synthesis of carbohydrates during the process of photosynthesis.
During electron transport the thylakoid space becomes?
During electron transport in the thylakoid membrane, the thylakoid space becomes more acidic (lower pH) as protons are pumped into this space by electron transport chain components, creating a proton gradient. This proton gradient is essential for ATP synthesis during the light reactions of photosynthesis.
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 the light dependet reactions with stroma or granum?
The light-dependent reactions of photosynthesis occur in the thylakoid membranes of the chloroplasts, specifically in the grana. The grana are stacks of thylakoid membranes where the light-dependent reactions take place. The stroma, on the other hand, is the fluid-filled space surrounding the grana where the Calvin cycle (light-independent reactions) occurs. So, the light-dependent reactions primarily occur in the grana, not the stroma.
