Where Do The Light-independent Reactions Of Photosynthesis 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.

Where do light-independent reactions occur quizlet?

The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma the fluid-filled area of a chloroplast outside of the thylakoid membranes.

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 dependent reaction occur?

Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.

Where do the light reactions of photosynthesis occur quizlet?

– The light reactions take place inside the thylakoids of chloroplasts.

Where do the light-dependent reaction and the Calvin cycle occurs in the chloroplast?

Light-dependent reaction takes place in the presence of light energy in thylakoid membranes (grana) of the chloroplast Calvin cycle occurs at the stroma of the chloroplast.

What three reactions occur during the light reactions in photosynthesis?

Light reactions harness energy from the sun to produce chemical bonds ATP and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation reduction and regeneration.

Which is formed during the Light-independent phase of photosynthesis?

What is formed during the light-independent phase of photosynthesis? Glucose molecule.

Where does the light reaction occur in chloroplast?

The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There water (H2O) is oxidized and oxygen (O2) is released.

Where do Calvin cycle reactions occur?

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 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.

Where in the chloroplast does the light reaction occur 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.

Is the Calvin cycle light-dependent?

The Calvin cycle refers to the light-independent reactions in photosynthesis that take place in three key steps. Although the Calvin Cycle is not directly dependent on light it is indirectly dependent on light since the necessary energy carriers ( ATP and NADPH) are products of light-dependent reactions.

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.

Which one of these reactions occurs during photosynthesis?

During photosynthesis plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell the water is oxidized meaning it loses electrons while the carbon dioxide is reduced meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Which is a light-independent reaction?

The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.

What does light-independent reactions produce?

Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions) drives this metabolic pathway.

Does light-independent reaction occur at night?

The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process. Although the light-independent reactions do not use light as a reactant (and as a result can take place at day or night) they require the products of the light-dependent reactions to function.

How does light reaction occur?

The light reaction occurs in the thylakoids of the chloroplast. When the light hits chlorophyll a get excited to higher energy state followed by a series of reactions. This energy is converted into energy molecules ATP and NADPH by using PS I and PS II.

Where does Calvin cycle occur in 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 does the Calvin cycle occur quizlet?

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

Where does Calvin cycle take place in C3 plants?

In the C3 plants the first compound form is of 3 carbon (PGA) while in C4 plants the first compound is of 4 carbon (OAA). The Calvin cycle takes place in the mesophyll cells. The Calvin cycle takes place in the bundle sheath cells.

Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment quizlet?

In a dark environment the process involved in the light-independent pathway slows down. When leaf disks are placed in a dark environment they begin to shrink and do not continue with the process.

Which of the following are generated by light reactions of photosynthesis quizlet?

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 is the light energy converted into an electron?

the reaction center is where light energy is converted into electron transport.

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.

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 light harvesting reactions occur in a eukaryotic cell?

In eukaryotic cells both the light and dark reactions of photosynthesis occur within chloroplasts—the light reactions in the thylakoid membrane and the dark reactions within the stroma. This section discusses the light reactions of photosynthesis which are related to oxidative phosphorylation in mitochondria.

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.
