What is produced in the stroma in the light-independent reactions?

What is produced in the stroma in the light-independent reactions?

3.6), also called the cycle of light-independent reactions of photosynthesis. The chemical reactions are carried out in the stroma that converts carbon dioxide into glyceraldehyde 3-phosphate (G3P), consuming the ATP and NADPH produced during the photophosphorylation process.

Do light reactions occur in the stroma?

The light reaction takes place in the thylakoid discs. Note that the dark reaction takes place in the stroma (aqueous fluid surrounding the stacks of thylakoids) and the cytoplasm.

Which one is correct light reaction occurs in stroma?

(i) Light reactions occur in grana thylakoids whereas dark reactions occur in stroma of chloroplasts.

What are the light independent products?

The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH. The reactants of light-independent reactions are ATP, NADPH, and Carbon Dioxide.

What is the process of light independent reaction?

The light independent process (also called dark reactions or the Calvin-Benson cycle) takes place in the stroma of the chloroplast. Carbon dioxide is modified by series of chemical reactions to form carbohydrates. The energy for these reactions comes from ATP and NADPH generated during the light dependent process.

Where does the light-independent cycle occur?

The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast’s own genetic material (separate from that of the cell) is also stored in the stroma.

Why do dark reactions occur in stroma?

In the dark reaction, plants use carbon dioxide with ATP and NADPH from the light reactions to produce glucose….

Light reactions Dark reactions
It takes place in the grana of the chloroplast. It occurs in the stroma of the chloroplast.

Why are the reactions of the Calvin cycle also called the light-independent reactions?

Overview of the Calvin cycle These reactions are also called the light-independent reactions because they are not directly driven by light. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

What is dependent reaction?

Light-dependent Reactions Definition Those reactions which occur in the presence of light (photons) are known as light-dependent reactions. The molecules of chlorophyll actively take part in the reaction. They transfer sunlight (solar energy) into potential energy and store it as chemical energy in sugars.

Where do the dark reactions occur?

The dark reaction occurs in the stroma of the chloroplast, where they utilize the products of the light reaction. Plants capture the carbon dioxide from the atmosphere through stomata and proceed to the Calvin cycle.
