What is produced from the light-dependent reactions of photosynthesis that are used in the dark reactions?

Explanation: End products of the Light reaction are ATP NADPH and Oxygen. Oxygen escapes into the atmosphere. ATP & NADPH which is produced is called Assimilatory Power and this will be used in dark reactions of Photosynthesis.

What are the products of light reaction that are used in the Calvin cycle?

ATP and NADPH are the two products of the light reactions that are used up in the Calvin cycle.

What are the end products of the light-dependent reaction Brainly?

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 is the product waste of light-dependent reactions of photosynthesis?

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. … This process illustrates oxygenic photosynthesis wherein the first electron donor is water and oxygen is created as a waste product.

What are the products of the Calvin cycle?

Products. The immediate products of one turn of the Calvin cycle are 2 glyceraldehyde-3-phosphate (G3P) molecules 3 ADP and 2 NADP+. (ADP and NADP+ are not really “products”. They are regenerated and later used again in the Light-dependent reactions).

Which of the answer choices are products of the light-dependent reactions of photosynthesis that are required by reactions in the Calvin cycle?

ATP and NADPH produced by the light reactions are used by the Calvin cycle to make carbohydrates. In the first step of photosynthesis ATP and NADPH are produced using the light-dependent reactions.

Where do light reactions produce ATP?

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).

Why are light-dependent reactions important to the Calvin cycle?

Why are the light-dependent reactions important to the Calvin cycle? The light-dependent reactions provide the Calvin cycle with ATP and NADPH. The Calvin cycle uses the energy in ATP and NADPH to produce high-energy sugars.

What happens in PSII?

PSII is the multisubunit chloroplast membrane-associated pigment–protein complex that uses the energy of sunlight to drive the oxidation of water evolving oxygen donating electrons into the photosynthetic electron transfer chain and depositing protons into the thylakoid lumen.

What is the purpose of light reaction in photosynthesis?

The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.

Why do dark reactions depend on light reactions?

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. … So although the cycle itself doesn’t use light energy it does depend on the light reactions to provide it with the ATP and NADPH.

What does light-dependent reaction produced at the end of the reaction?

The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH.

What are the end product of light depends reaction?

ATP and NADPH2 are the product of light-dependent reactions which reduces CO2 into carbohydrate in the light-independent reactions and oxygen is evolved.

What are the end products of light-dependent reactions Class 10?

The end products of the light reaction are ATP and NADPH also known as assimilatory powers.

Which best lists the end products of the light-dependent reactions of photosynthesis?

Which best list the end products of the light dependent reactions of photosynthesis? ATP NADPH and 02. During the light dependent reactions of photosynthesis light energy is converted into which form of energy? Chemical.

What provides electrons for the light reactions?

Light reactions occur when plants synthesize food from carbon dioxide and water referring specifically to the part of energy production that requires light and water to generate electrons needed for further synthesis. Water provides the electrons by splitting into hydrogen and oxygen atoms.

What is the main product of the Calvin cycle quizlet?

The product of the Calvin cycle is a triose-phosphate sugar that is either exported from the chloroplast or used to regenerate RUBP.

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.

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.

Where does 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.

What are the important events and products of light reaction?

Answer: The important events of light reaction are (i) Excitation of chlorophyll molecule to emit a pair of electrons and use of their energy in the formation of ATP from ADP + Pi. This process is called photophosphorylation. Splitting of water molecule (a) (b) End products of light reaction are NADPH and ATP.

What happens to oxygen produced by the light-dependent reactions?

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.

What is produced in the light dependent reaction and used in the Calvin cycle?

The Calvin cycle is the term used for the reactions of photosynthesis that use the energy stored by the light-dependent reactions to form glucose and other carbohydrate molecules (Figure 1). Figure 1 The light-dependent reactions harness energy from the sun to produce ATP and NADPH.

What molecules are made in PSII?

Photosystem II obtains replacement electrons from water molecules resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2) which is released into the atmosphere.

What does photosynthesis produce?
