Where do the light-dependent reactions take place quizlet?

In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.

Where do the light reactions light-independent take place?

stroma

Where do light-independent reactions occur? The Calvin cycle or light-independent reaction of photosynthesis happens in the stroma of the chloroplast. It has certain enzymes that work with NADPH and ATP. They form carbon-containing molecules (such as glucose molecules) from carbon dioxide.

What are light-dependent reactions quizlet?

light dependent reactions. reactions of photosynthesis that use energy from light and water to produce ATP and oxygen that is released into the atmosphere.

Where does the light dependent reaction of photosynthesis occur what is produced quizlet?

The light-dependent reactions require light and water, occur in the thylakoids, and produce ATP and NADPH.

Where do the light reactions take place in the chloroplast?

the thylakoid

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. The electrons that freed from the water are transferred to ATP and NADPH.

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

stroma

In plants, carbon dioxide (CO2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis.

Where does Calvin cycle take place?

stroma
Overview of the Calvin cycle This process is fueled by, and dependent on, ATP and NADPH from the light reactions. 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).

How does light enter the light-dependent reactions quizlet?

Light energy is converted into chemical energy in the form of the energy-carrying molecules ATP and NADPH. Where do light dependent reactions take place? absorbs sunlight causing 2 electrons to become excited and leave Photosystem II. The electrons pass down a transport chain generating ATP cytochrome complex.

What is the function of the light-dependent reactions quizlet?

The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules.

  • Formula for photosynthesis. 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Which events take place in light-dependent reactions of photosynthesis?

The light-dependent reactions release oxygen as a byproduct as water is broken apart. In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.

What occurs in light-dependent reactions?

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. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

What occurs in the light dependent?

In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.

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.

Where does Calvin cycle take place 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).

What are the light-dependent and light-independent reactions of photosynthesis?

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Where do CAM plants store co2?

CAM plants have a different leaf anatomy from C3 plants, and fix the CO2 at night, when their stomata are open. CAM plants store the CO2 mostly in the form of malic acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which is then reduced to malate.

Does the light-independent reaction occur in the dark?

There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is called the “dark reaction”, the Calvin cycle does not actually occur in the dark or during night time.

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.

What are the inputs to the Calvin cycle where do they come from?

The inputs to the Calvin cycle are CO₂, ATP, and NADPH. The CO₂ comes from the atmosphere around the plant, and the ATP and NADPH come from the light-dependent reaction.

Where do respiration and cellular respiration takes place?

mitochondria
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.Feb 12, 2020

Where in the chloroplast does the light-dependent reaction occur 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 in the chloroplast do the light reactions 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.

What items are needed for the light-dependent reactions to take place?

What two things are needed for the light-dependent reactions to take place? –Water and light are needed for light-dependent reactions.

Where in a plant cell is chlorophyll found?

chloroplasts

There are many different types of pigments in nature, but chlorophyll is unique in its ability to enable plants to absorb the energy they need to build tissues. Chlorophyll is located in a plant’s chloroplasts, which are tiny structures in a plant’s cells.

What are the three parts of the light-dependent reaction?

Where does light independent reaction reactants and products?

GA3P and oxygen are products. In photosynthesis, water, carbon dioxide, ATP, and NADPH are reactants. RuBP and oxygen are products. In photosynthesis, water and carbon dioxide are reactants.

Where do the light-independent reactions take place and identify the 4 reaction steps?

Inside the chloroplasts, the Calvin cycle reactions take place in the stroma. The reactants CO2, ATP and NADPH initiate the four-step reactions that make up the Calvin cycle.

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.

Where do each of these reactions take place in photosynthesis?

The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).

Where does water in the light-dependent reaction come from?

The light-dependent reactions begin in photosystem II. In PSII, energy from sunlight is used to split water, which releases two electrons, two hydrogen atoms, and one oxygen atom.

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.

Where do light reactions produce ATP?

thylakoid membrane

Photosystem I

A proton gradient is created across the thylakoid membrane (6) as protons (3) are transported from the chloroplast stroma (4) to the thylakoid lumen (5). Through chemiosmosis, ATP (9) is produced where ATP synthase (1) binds an inorganic phosphate group (8) to an ADP molecule (7).
