Where is the ATP produced during the light reaction?

thylakoid membrane

In respect to this, how is ATP produced in light reactions?

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.

Secondly, how many ATP are produced in the light reactions? 2 ATP

Similarly one may ask, where does light reaction take place?

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 electrons get their energy in the light reactions?

Light reactions -- light energy in the presence of chlorophyll -- splits water. Splitting water into oxygen gas, hydrogen ions and electrons produces the energy for subsequent electron and proton transport and provides the energy to produce the sugars the plant needs. These subsequent reactions form the Calvin cycle.

Similar Question and The Answer

What are the products of light reactions?

The products of the light reactions are ATP and NADPH. These products are generated by the electron transport chains in the chloroplasts.

What are the reactants and products of light dependent reactions?

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

What is ATP and Nadph?

ATP and NADPH are the main product of the Light reactions of photosynthesis. ATP provides the free energy to power the Calvin Cycle (a.k.a. the Dark reactions). NADPH is the key electron donor (reducing agent). This provides the hydrogen and electrons needed to combine carbon dioxide into carbohydrate molecules.

How many ATP are produced in Noncyclic Photophosphorylation?

Because 6 turns of non cyclic photophosphorylation will produce 12 NADPH2 and 6 ATP molecules. And cyclic photophosphorylation will produce 12 ATP molecules.

What is the process of light dependent reaction?

The overall function of light-dependent reactions, the first stage of photosynthesis, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.

What are the three stages of the Calvin cycle?

The Calvin cycle reactions (Figure 2) can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP).

What are the products of the Calvin cycle?

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.

Why is the process of Chemiosmosis also called the light dependent reactions?

The flow of hydrogen ions through ATP synthase is called chemiosmosis, because the ions move from an area of high to low concentration through a semi-permeable structure.

What is a stack of thylakoids called?

A granum (plural grana) is a stack of thylakoid discs. Chloroplasts can have from 10 to 100 grana. Grana are connected by stroma thylakoids, also called intergranal thylakoids or lamellae.

What is light reaction in biology?

Definition. The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH. Supplement. The light reactions take place on the thylakoid membranes of the chloroplast.

Where do the light reactions occur in the 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. The electrons that freed from the water are transferred to ATP and NADPH.

What is a cyclic Photophosphorylation?

Cyclic photophosphorylation can be defined as the synthesis of ATP coupled to electron transport activated by Photosystem I solely, and can therefore proceed in long-wave-length light (03BB 2265 700 nm). This proces is unaffected by the specific inhibitors of Photosystem II, such as CMU, DCMU and orthophenanthroline.

What's the difference between light dependent and light independent reactions?

Light dependent part of photosynthesis is concerned with production of ATP and NADPH2 utilizing solar energy. Light independent part of photosynthesis involves reduction of CO2 to C6H12O6 .

What is the difference between light reaction and dark reaction?

What is the difference between light and dark reaction? The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.

How long it takes to cook dumpling?

Cook the dumplings for 3 to 5 minutes if fresh, or 6 to 8 minutes if frozen: When done, the wrappers will appear translucent and noodle-like; the filling will be opaque and warmed through (you can cut one open to check). Also asked, how long should dumplings cook? Bring a large pot of water to a boil . Cook dumplings in batches of about 8 until they are cooked through, 3 to 4 minutes . Using a slotted spoon, transfer the dumplings to a serving platter. Serve warm with the dipping sauce. Secondly, do dumplings float when done? So, altogether, the starch molecules do not absorb much more water as they are done , so the remaining water can vaporize and fill the air pockets, which makes the dumpling float then. Or, in other words, a floating dumpling is actually overcooked and so guaranteed to be ready (if the preconditions are met). Secondly, how do you know when dumplings are cooked? To test the dumplings , run a skewer or a toothpick through one. When it comes out clean,
