What is the fate of electrons in noncyclic photophosphorylation?
Wiki User
∙ 11y ago
The electrons released by P700 of PS-I in the presence of light are taken up by the primary acceptor and are then passed on to ferredoxin (Fd), plastoquinone (PQ), cytochrome complex, plastocyanin (PC) and finally back to P700 i.e., electrons come back to the same molecule after cyclic movement.

Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?
water
What are the products of a non-cyclic electron flow?
In photosynthesis, the noncyclic electron flow produces enzymes called cytochrome b6f complex. Its function is to catalyze the electron transfer of plastoquinol to plastocyanin.
Photophosphorylation differs from oxidative phosphorylation in that?
in oxidative phosphorylation, the H+ moved out of the cell using the channel proteins that make up the ETC (electron transport chain) and then they flow back into the mitochondria through the ATP synthase because of the concentration gradient. Photophosphorylation has its H+ ions travelling in the opposite direction (from inside to outside of the chloroplasts through ATP synthase. Another difference is the fact that in photophosphorylation the H+ are produced by splitting water while the H+ in oxidative phosporylation come from H+ that have been removed from compounds and have had their electrons removed by NAD+ or FAD.
How is the energy used to make ATP via the electron transport chain generated?
It is enerated in plants during the process photophosphorylation (aka. photosynthesis) It is generated in plants through the process of photophosphorylation, in the thylakoid membranes of chloroplasts.
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
In noncyclic photophosphorylation what is the ultimate acceptor of electrons that have been produced from the splitting of water?
Carbon dioxide is a noncyclic photophosphorylation and is the ultimate acceptor of electrons that have been produced from the splitting of water. A product of both cyclic and noncyclic photophosphorylation is ATP.
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from?
The electrons that are passed to NADPH during noncyclic photophosphorylation were obtained from water. The ultimate electron and hydrogen acceptor in the noncyclic pathway is NADPH+.
Which process requires electrons that are obtained by the splitting of water A cyclic photophosphorylation B noncyclic photophosphorylation C Photorespiration?
The answer is A) Cyclic Photophosphorylation
What is the fate of the NADPH molecules created during noncyclic photophosphorylation?
They are used in the Calvin-Benson cycle.
What is produced by noncyclic photophosphorylation and used by the Calvin cycle?
ATP and NADPH
Is oxygen created during NADPH?
No, oxygen is created from the splitting of water as a waste product. After the electrons from the splitting of water go through photosystem 2 & 1, they would be used to create NADPH in noncyclic photophosphorylation.
What is cyclic and non cyclic?
Cyclic photophosphorylation is when the electron from the chlorophyll went through the electron transport chain and return back to the chlorophyll. Noncyclic photophosphorylation is when the electron from the chlorophyll doesn't return back but incorporated into NADPH.
Origin of oxygen as a byproduct of noncyclic photophosphorylation?
Plant, green algae and some bacterial photosynthesis depend on noncyclic electron flow, which means that electrons lost by the photosystems are not recycled back to the photosystems but instead passed on to NADPH. To replenish electrons lost by the photosystems, these organisms rely on an oxygen evolving complex (mechanism not well understood) that split water into protons, electrons, and oxygen. The electrons are used to replenish electrons lost by the photosystems, the protons are used to generate the proton gradient used to produce ATP, and oxygen, not used by the plant, leaves as a byproduct.
