Where would light-independent reactions take place?

stroma

The light-independent reactions represent the known Calvin–Benson–Bassham (CBB) cycle which takes place in the stroma of chloroplasts and is the primary pathway of carbon fixation of C3 plants [119]. The CBB cycle proceeds in three main stages: carboxylation, reduction and regeneration.

Where do the light dependent and light-independent reactions take place in photosynthesis?

The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.

Where does the light reaction of photosynthesis take place quizlet?

– The light reactions take place inside the thylakoids of chloroplasts. – The light reactions produce chemical energy in the form of NADPH and ATP.

Where does photosynthesis take place?

chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

What reaction takes place during photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

How are the light-dependent and light-independent reactions of photosynthesis related quizlet?

The light-dependent reactions of photosynthesis use water and produce oxygen. … The light-independent reactions release energy, and the light-dependent reactions require energy. The light-dependent reactions pass electrons through an electron transport chain to the light-independent reactions.

Where does Calvin cycle take place?

stroma

The Calvin Cycle occurs in the stroma of a chloroplast in a plant cell. The stroma is the colorless fluid that surrounds the grana of the chloroplast, where the first step of photosynthesis takes place.

Where does the light independent reaction Calvin cycle take place within the chloroplast?

stroma
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).

Where in the chloroplast do the light reactions take place quizlet?

Within the chloroplast, the light reactions take place in the flattened sacs called thylakoids and the Calvin cycle takes place in the thick fluid called the stroma.

Where in the chloroplast do the light-dependent reactions take place quizlet?

The light-dependent reactions take place on the thylakoid membranes (the light is absorbed by the chlorophyll that is embedded in these membranes). The light-independent reactions (also called the Calvin Cycle or the dark reactions) take place in the stroma. The stroma is the fluid that fills the chloroplast.

Where does light stage of photosynthesis occur?

The chloroplast is involved in both stages of photosynthesis. The light reaction takes place in the thylakoid discs. There, water (H20) is oxidized, and oxygen (O2) is released. The electrons freed up from water are transfered to ATP and NADPH.

Where in the chloroplast does photosynthesis take place?

Photosynthesis: The Basics

Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).

Where does photosynthesis take place and why?

Photosynthesis, a plant’s internal process that converts light energy into food, takes place mostly in the leaves of plants. Plants and trees utilize specialized structures to conduct the chemical reactions necessary to transform sunlight into chemicals the plant can use.

What do the light-dependent reactions of photosynthesis produce?

The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.

What reaction takes place during photosynthesis Mcq?

Therefore, Photosynthesis is an Oxidation-Reduction reaction which takes place in two steps; light reaction and dark reaction. With the help of Question and Answers we have tried to cover the whole process and also we come to know how light energy is converted into chemical energy.

What type of reaction occurs during photosynthesis apex?

The light-independent reactions of photosynthesis—also known as the Calvin cycle—use enzymes in the stroma, along with the energy-carrying molecules (ATP and NADPH) from the light-dependent reactions, to break down carbon dioxide molecules (CO2) into a form that is used to build glucose.

What do the light reactions of photosynthesis supply the Calvin cycle with?

The light reactions produce carbon dioxide, ATP, NADPH, all of which are used in the Calvin cycle. The light reactions produce ATP and NADPH, both of which are used in the Calvin cycle.

Where does the Calvin cycle take place quizlet?

Where does the Calvin Cycle occur? The Calvin Cycle occurs in the stroma, whereas the light reactions occur in the thylakoids.

Where does the Calvin cycle take place in C3 plants?

stroma
The Calvin cycle, Calvin–Benson–Bassham (CBB) cycle, reductive pentose phosphate cycle (RPP cycle) or C3 cycle is a series of biochemical redox reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Where does Calvin cycle or dark reaction occur?

The Calvin cycle is also called the dark reactions or light-independent reactions because it is the part that doesn’t need energy from the sun to happen. The Calvin cycle takes place within the stroma of the chloroplast.

What happens during the Calvin cycle How does the Calvin cycle depend on the light reactions?

How does the Calvin cycle depend on the Light reactions? –The ATP provides the energy, and the NADPH supplies the electrons for the Calvin cycle, which converts carbon dioxide to sugar. The ADP and NADP+ that result from the Calvin cycle shuttle back to the light reactions, which regenerate ATP and NADPH.

What are the inputs of the light-dependent reactions?

2. Inputs to the light reactions are water and the light energy. 3. The light reactions produce ATP, NADPH and Oxygen.

Why do the light-dependent reactions of photosynthesis take place in the thylakoid quizlet?

-The purpose of the light-dependent reactions is to use water and light to produce ATP and NADPH or energy that the cell can use. … -Light-dependent reactions happen in the thylakoid membrane. -The Calvin Cycle happens in the stroma.

Where do the light reactions occur in plant cells quizlet?

1) The light reactions occur in the thylakoid membrane. 2) The inputs to the light reaction is water and light.

What is light independent reaction quizlet?

The light-independent reaction: The second and final stage of photosynthesis. It uses the products of the light-dependent reaction (ATP and reduced NADP) to make organic substances for the plant. The Calvin Cycle. AKA the Light-Independent Reaction.

What process occurs during the light-independent reactions?

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 reaction takes place Class 10?

The light reaction is also known as photolysis reaction and takes place in the presence of light. It usually takes place in the grana of chloroplasts.

Does light reaction take place in Grana?

A light reaction takes place in the grana of chloroplast.

Where does the first stage of photosynthesis take place?

chloroplasts

The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast.

How does photosynthesis take place in the thylakoid?

Photosynthesis occurs in the chloroplast, an organelle specific to plant cells. The light reactions of photosynthesis occur in the thylakoid membranes of the chloroplast. Electron carrier molecules are arranged in electron transport chains that produce ATP and NADPH, which temporarily store chemical energy.

Why does photosynthesis take place in the leaves?

Photosynthesis primarily happens in green leaves (not colorful autumn leaves). Leaves are ideal for photosynthesis because they are usually broad and flat, giving plenty of surface area for light to be absorbed. They are also thin, which means diffusion of gases such as carbon dioxide can happen quickly.

What are the two location of photosynthesis?

chloroplasts

Location of Photosynthesis

Photosynthesis occurs in chloroplasts found in the leaves and green stems of plants.

Where do electrons come from in light-dependent reactions?

In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain. The two photosystems absorb light energy through proteins containing pigments, such as chlorophyll.
