The carbon fixation reactions take place in the stroma of the chloroplast. This is the fluid-filled space surrounding the thylakoids, where enzymes catalyze the conversion of carbon dioxide into organic molecules during the Calvin cycle. The stroma contains the necessary components, such as ribulose bisphosphate (RuBP) and various enzymes, to facilitate this process.
What else can I help you with?
What part of a chloroplast is not involved in the light reactions?
The stroma of a chloroplast is not directly involved in the light reactions. Instead, it is the site of the Calvin cycle, where carbon fixation occurs and glucose is synthesized using the ATP and NADPH produced during the light reactions. The light reactions primarily take place in the thylakoid membranes, where sunlight is captured and converted into chemical energy.
Where and when does carbon fixation occur in photosynthesis?
in the stomata, prior to the Calvin cycle
Where is rubisco most active in?
Rubisco is most active in the stroma of chloroplasts, which is where the Calvin cycle takes place. Rubisco's main function is to catalyze the first step of carbon fixation in photosynthesis, converting carbon dioxide into organic molecules.
Where does the Calvin Cycle occur in C3 plants?
The Calvin Cycle occurs in the stroma of the chloroplast in C3 plants. This cycle is part of the light-independent reactions of photosynthesis where carbon dioxide is converted into sugar molecules using ATP and NADPH generated during the light-dependent reactions.
Where do the light-idependent reactions pf photosynthesis take place?
The light-independent reactions of photosynthesis take place in the stroma of the chloroplasts. This is where carbon fixation and the Calvin cycle occur, utilizing the products of the light-dependent reactions to produce glucose.
Where do most carbon fixation reactions take place in plants?
the stroma

How does light and dark reactions takes place?
The light dependent reaction occurs in the chloroplast. In the light dependent reaction, chlorophyll pigments absorb solar energy. This energy is then converted into a chemical form (not glucose). The water molecule is split into oxygen and hydrogen molecules. The dark reaction or the carbon fixation period occurs in the fluid matrix or stroma of chloroplast. The hydrogen product from the first reaction is combined with the carbon dioxide molecules to makes sugars. This results in the C3 or C4 cycle.
Which part of the chloroplast does the calvin cycle occur in?
The Calvin cycle, which is the process of carbon fixation in photosynthesis, occurs in the stroma of the chloroplast. This is where the enzymes and molecules involved in the cycle are located, allowing for the conversion of carbon dioxide into glucose.
Where in the cell does light independent reactions take place?
Light-independent reactions, also known as the Calvin cycle, take place in the stroma of the chloroplast. This part of the chloroplast surrounds the thylakoid membranes where the light-dependent reactions occur. In the stroma, carbon dioxide is fixed and converted into glucose through a series of enzymatic reactions.
Where is rubisco most active in?
Rubisco is most active in the stroma of chloroplasts, which is where the Calvin cycle takes place. Rubisco's main function is to catalyze the first step of carbon fixation in photosynthesis, converting carbon dioxide into organic molecules.
Where does the Calvin Cycle occur in C3 plants?
The Calvin Cycle occurs in the stroma of the chloroplast in C3 plants. This cycle is part of the light-independent reactions of photosynthesis where carbon dioxide is converted into sugar molecules using ATP and NADPH generated during the light-dependent reactions.
During which stage of photosynthesis does carbon fixation take place?
Carbon fixation takes place during the Calvin cycle, which is the second stage of photosynthesis. In this process, carbon dioxide from the atmosphere is converted into organic compounds by using the energy obtained from light-dependent reactions.
Where do 'dark reactions' take place?
Dark reactions, also known as the Calvin cycle, take place in the stroma of chloroplasts in plant cells. These reactions use the products of the light-dependent reactions to convert carbon dioxide into glucose through a series of enzyme-catalyzed steps.
What is the place where dark reactions occur?
Stroma of the chloroplast
Where do the light-idependent reactions pf photosynthesis take place?
The light-independent reactions of photosynthesis take place in the stroma of the chloroplasts. This is where carbon fixation and the Calvin cycle occur, utilizing the products of the light-dependent reactions to produce glucose.
