What are the products of linear electron flow during light reaction?
The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions.
What are the products of linear electron flow quizlet?
A route of electron flow during the light reactions of photosynthesis that involves both photosystems and produces ATP, NADPH, and oxygen. The net electron flow is from water to NADP+. linear pathway that leads to NADPH, ATP, and O2 production, pathway is similar to Electron transport chain.
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.
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).
What are the products of linear electron transport and cyclic electron transport What is the role of cyclic electron transport?
Linear electron transport generates both ATP and NADPH, whereas PSI cyclic electron transport produces ATP without producing NADPH. PSI cyclic electron transport is thought to be essential for balancing the ATP/NADPH production ratio and for protecting both photosystems from damage caused by stromal overreduction.

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.
What is the difference between linear electron flow and 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 products of cyclic electron flow during the light reactions of photosynthesis?
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
What is produced in cyclic electron flow?
Cyclic electron flow is increasingly recognized as being essential in plant growth, generating a pH gradient across thylakoid membrane (ΔpH) that contributes to ATP synthesis and triggers the protective process of nonphotochemical quenching (NPQ) under stress conditions.
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.
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).
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.
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 .
