What are the products of linear electron flow during light reaction?
A route of electron flow during the light reactions of photosynthesis that involves both photosystems and produces ATP, NADPH, and oxygen.
What is produced during linear electron transport?
Linear electron transport results in the formation of reductant and ATP, while cyclic electron transport results only in the formation of ATP with no net formation of reductant. The flux of electrons through these pathways is regulated at the level of the cytb6f complex.
What are the reactants of linear electron flow?
Introduction. During oxygenic photosynthesis in plants, leaves absorb light energy to drive photosynthetic electron flow in the chloroplasts. In linear electron flow (LEF), electrons from the splitting of water by the oxygen-evolving complex (OEC) are transferred to NADP+, reducing NADP+ to NADPH.
Is oxygen a products of linear electron flow?
Explanation: Oxygen is in fact a by product of light dependent reactions of photosynthesis. During light reaction of photosynthesis, In non-cyclic electron flow, when Photosystem II absorbs light, an electron is excited to a higher energy level in the reaction center of Chlorophyll P680 .
What is produced during cyclic electron flow?
In cyclic electron flow (CEF), electrons are recycled around photosystem I. As a result, a transthylakoid proton gradient (ΔpH) is generated, leading to the production of ATP without concomitant production of NADPH, thus increasing the ATP/NADPH ratio within the chloroplast.
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).
How does linear electron flow produce ATP and NADPH?
The primary electron acceptor of photosystem I passes the excited electrons to a second electron transport chain which transmits them to an iron-containing protein. An enzyme reaction transfers the electrons from the protein to NADP+ that forms NADPH (which has high chemical energy due to the energy of the electrons).
What is produced from non cyclic electron flow?
In a process called non-cyclic photophosphorylation (the "standard" form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .
What are the 3 products of linear photophosphorylation?
What are the three products of linear electron flow? Linear Electron Flow produces: NADPH—electron donor used to reduce CO2 to sugar in the Calvin Cycle. ATP—energy source for the Calvin Cycle. O2—released as by-product.
What happens in linear electron flow?
In linear electron flow (unbroken arrows) energy from absorbed photons is used to oxidise water on the luminal face of photosystem II (PS II). Electrons generated by this process pass through a series of electron carriers in PS II and then to the oxidized plastoquinones (PQ) that diffuse within the membrane.
Does linear electron flow produce ATP?
In linear electron flow (LEF), the PSs function in series and electrons are transferred all the way from water to NADP+ with concomitant production of NADPH and ATP.
What are the products of linear photophosphorylation?
The products of linear photophosphorylation ATP and NADPH are used in the light-independent reactions of photosynthesis (also termed the carbon fixation cycle or the Calvin cycle).
What is the final product of Calvin cycle?
glucose The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.
What are the products of the light reactions and the Calvin cycle?
How the products of the light reactions, ATP and NADPH, are used to fix carbon into sugars in the second stage of photosynthesis.
How many ATP and NADPH are produced in non-cyclic photophosphorylation?
Non-cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules.
What are the products of non-cyclic photophosphorylation?
The net result of non-cyclic phosphorylation is the formation of NADPH, oxygen and ATP molecules. Oxygen is produced as a waste product of photosynthesis.
What are the products of linear photophosphorylation quizlet?
21) What are the products of linear photophosphorylation? Source Page 193 – The two photosystems work together in using light energy to generate ATP and NADPH , the two main products of the light reactions. Source Figure 10.14 – How a linear electron flow during the light reactions generates ATP and NADPH.
What is produced in cyclic electron flow?
In cyclic electron flow (CEF), electrons are recycled around photosystem I. As a result, a transthylakoid proton gradient (ΔpH) is generated, leading to the production of ATP without concomitant production of NADPH, thus increasing the ATP/NADPH ratio within the chloroplast.
How does linear electron flow differ from cyclic electron flow?
In linear electron flow (LEF), the PSs function in series and electrons are transferred all the way from water to NADP+ with concomitant production of NADPH and ATP. Cyclic electron flow (CEF), in contrast, recycles electrons around PSI by re-routing them from ferredoxin (Fd) to the plastoquinone (PQ).
What are the 3 products of Calvin cycle?
Products of Calvin Cycle Generally, the carbohydrate products of the Calvin cycle are the three carbon sugar phosphate molecules or the triose phosphates (G3P). The products formed after a single turn of the Calvin cycle are 3 ADP, 2 glyceraldehyde-3-phosphate (G3P) molecules, and 2 NADP+.
Which product is formed in 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).
What are the 3 products produce during light reaction?
These are the molecules necessary to begin the process. But one more item is necessary, and that is sunlight. All three components, carbon dioxide, water, and the sun's energy are necessary for photosynthesis to occur. These three components must meet in the chloroplast of the leaf cell for photosynthesis to occur.
How many ATP are produced in noncyclic electron transport chain?
1 ATP Non-cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules.

What are the products of non cyclic Photophosphorylation?
The net result of non-cyclic phosphorylation is the formation of NADPH, oxygen and ATP molecules. Oxygen is produced as a waste product of photosynthesis.
What is the main product of the electron transport chain?
The electron transport chain produces the most ATP out of all the steps, producing 28 molecules of ATP. This results in a total of 32 ATP molecules for the entire process of cellular respiration.
What is produced from non-cyclic electron flow?
In a process called non-cyclic photophosphorylation (the "standard" form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .
What are the end products of 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.
What are the outputs of the Calvin cycle?
Outputs of the Calvin cycle are ADP, P, and NADP+, which go into the light reactions, and sugar, which is used by the plant. 2.
What are the products of photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
