Where In The Chloroplast Does The Calvin Cycle Occur?

Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

Similarly, Where in the chloroplast does the Calvin cycle occur quizlet?

1) The chloroplast’s stroma is where the Calvin Cycle takes place. NADPH, ATP, and CO2 serve as the Calvin cycle’s inputs.

Also, it is asked, Why does Calvin cycle occur in stroma?

Sun energy is used by light-dependent processes to create ATP and NADPH. These molecules go towards the stroma, where the Calvin cycle processes take place, transporting energy.

Secondly, In which part of the chloroplast do the carbon fixation reactions take place?

stroma of chloroplasts

Also, Which occurs in the thylakoid?

The thylakoid discs are where the light response occurs. There, oxygen (O2) and water (H20) are released as a result of oxidation. ATP and NADPH get the released electrons from the water. The dark response takes place external to the thylakoids.

People also ask, In which part of a cell does the Calvin cycle take place quizlet?

What location does the Calvin cycle occur? in a chloroplast cell’s stroma.

Related Questions and Answers

Which of the following occurs in the stroma of the chloroplast?

The enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase is found in the chloroplast stroma, which is where the light-independent processes of photosynthesis take place (rubisco).

What is the part of the chloroplast where the light reaction does occur in presence of visible light?

The thylakoid is where the light responses happen. There, oxygen (O2) and water (H2O) are released as a result of oxidation.

Where does Calvin cycle occur in C3 plants?

What is Calvin cycle in photosynthesis?

The processes of photosynthesis that utilise the energy accumulated by the light-dependent reactions to create glucose and other carbohydrate molecules are known as the Calvin cycle.

Does the Calvin cycle occur in the dark?

The “reactions” of the Calvin cycle really take place at night. The truth of the matter is that a number of the so-called “dark processes” enzymes are really indirectly reliant on light to function.

In which stage of the Calvin cycle does the plant cell produce energy for storage?

Reduction. The 3-PGA molecules produced by carbon fixation are changed into molecules of glyceraldehyde-3 phosphate, a simple sugar, in the second step of the Calvin cycle (G3P). Energy for this phase comes from the ATP and NADPH produced during the photosynthesis’ light-dependent processes.

What happens in the grana?

Two stages are involved in photosynthesis. Chlorophyll in the grana absorbs light during the first reaction, known as the light reaction. The thylakoid membrane’s enzyme system transfers the light’s energy, culminating in the synthesis of the energy-carrying substances ATP and NADPH.

What does the thylakoid do in the chloroplast?

The interior membranes of cyanobacteria and chloroplasts, known as thylakoids, serve as a platform for the photochemical processes that take place during photosynthesis.

In which part of a chloroplast does photosynthesis occur quizlet?

What two regions of a chloroplast are where photosynthesis occurs? The Stroma and the Grana

Where in the chloroplast do the light reactions occur quizlet?

The Calvin cycle occurs in the thick fluid known as the stroma, while the light reactions occur in the flattened sacs known as thylakoids within the chloroplast.

Where does the Calvin cycle occur in eukaryotes?

In eukaryotes, photosynthesis occurs in chloroplasts; the Calvin cycle and light-harvesting reactions happen in the stroma and thylakoid membrane, respectively.

What happens in stroma of chloroplast?

The liquid that fills the inside space of the chloroplasts, which enclose the grana and the thylakoids, is known as stroma. The stroma are now understood to include chloroplast DNA, starch, and ribosomes in addition to the enzymes required for the Calvin cycle and maintain the pigment thylakoids.

What are grana in chloroplast?

A stacked section of the chloroplast’s thylakoid membrane is referred to as a “granum” (plural: “grana”). In photosynthesis’s light responses, grana play a role. Lamella: A sheet-like membrane that may be found in an autotrophic cell’s chloroplast.

Does the Calvin cycle take place in the mitochondria?

The stroma region of the chloroplasts is where the Calvin cycle occurs, as explained. Another organelle is the mitochondria, and the DNA is found in the nucleus. The pigment chlorophyll, which is where the light reactions take place, is found in the thylakoids, which are found in the chloroplasts.

What is the part of the chloroplast where the light reaction does occur in presence of visible light a stroma B Grana C stoma D cytoplasm?

The light reaction takes place in the granum region of the chloroplast when there is visible light present. The stroma makes up the remaining portion of the cytoplasm.

Which reaction occurs in Grana?

reaction of photosynthesis with light

Does light reaction occur in Grana?

The stack of thylakoids in the chloroplast is called the grana. These are the locations where light reactions occur to make ATP and NADPH.

Why is Calvin cycle also called C3 pathway?

The Calvin cycle is often known as the C3 cycle because the first stable molecule in the cycle has three carbons (3 phosphoglyceric acid). Calvin’s cycle responses take place in three stages.

Where does the Calvin cycle occur mastering biology?

The Calvin cycle takes place where? In the stroma, the Calvin cycle takes place.

Where does C4 photosynthesis occur?

cell mesophyll

What is C4 and CAM plants?

Typically, C4 plants are summer crops like maize and sugar cane. They can to some degree withstand extreme heat and a lack of water. CAM plants, on the other hand, are more appropriate for dry settings like deserts. Aloe vera and cacti are two CAM plants.

Does Calvin cycle require sunlight?

Since this process doesn’t directly need sunlight, it may alternatively be referred to as the “light-independent reaction” (but it does require the products produced from the light-dependent reactions).

Why does the Calvin cycle not occur at night?

Since the Calvin cycle doesn’t need sunshine, it is a dark reaction. Even though it might take place throughout the day, this procedure doesn’t need sunlight to function. The Calvin cycle is also known as the C3 route, the light-independent reaction, and the Calvin-Benson cycle.


The “where does the calvin cycle take place” is a question that many people ask. The answer to this question is not easy to find, but it can be found in the chloroplast.
