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+.
How photosystem I and II replenish its lost electrons?
Splitting of water molecules
Which part of the photosynthetic cycle involves an enzyme taking a molecule of NADP plus and adding two electrons and one proton to it?
The part of the photosynthetic cycle that involves an enzyme adding two electrons and one proton to NADP+ is known as the light-dependent reactions, specifically during the process of photophosphorylation. In this process, electrons are generated from the splitting of water molecules and are transferred through the electron transport chain, ultimately reducing NADP+ to NADPH. This NADPH then plays a crucial role in the subsequent light-independent reactions (Calvin cycle) to synthesize glucose.
When light is absorbed by chlorophyll molecules the excited electrons leave the molecule What is the source of electrons that makes chlorophyll stable again?
The source of electrons that makes chlorophyll stable again is water. The process of photosynthesis involves the splitting of water molecules to provide electrons, which are then used to replace the electrons lost from the chlorophyll molecule during absorption of light.
How is H electrochemical gradient established and maintained in photosynthesis?
The formation of NADPH, the movement of electrons from PSII to PSI, & the splitting of water
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+.
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.
Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?
water
Where do the electrons needed by the water-splitting photosystem originate?
The electrons needed for water-splitting in the photosystem originate from the splitting of water molecules during the light-dependent reactions of photosynthesis. Water molecules are split into oxygen, protons, and electrons by the photosystem II enzyme, providing the electrons needed to drive the electron transport chain.
The process of splitting water to release hydrogens and electrons occurs during the process a light dependent b light independent c carbon fixation d carbon photophosphorylation e glyc?
The process of splitting water to release hydrogen ion and electrons along with oxygen is called photolysis. Photolysis occurs during non-cyclic phase of photosynthesis. Photos means light and lysis means splitting. Thus it is evident from the name itself that photolysis is a light dependent step of photosynthesis.
Photophosphorylation differs from oxidative phosphorylation in that?
Photophosphorylation occurs in chloroplasts during photosynthesis, where light energy is used to generate a proton gradient and drive ATP synthesis. In contrast, oxidative phosphorylation occurs in mitochondria, where electrons are transferred along the electron transport chain to generate a proton gradient and drive ATP synthesis using energy released from the oxidation of nutrients.
Chemical bonds can be produced by any what processes except what?
splitting electrons
How photosystem I and II replenish its lost electrons?
Splitting of water molecules
Which term describes ATP production resulting from the capture of light energy by chlorophyll?
When the chloroplasts are exposed to light , some electrons in the atoms of the chlorophyll molecule gain energy , these electrons jump up & light energy is converted into kinetic energy , energy then is stored in form of potential chemical energy , electrons release the stored energy & thus they return to original energy levels part of released energy is stored in the form of ATP , other part is used in splitting H2O into hydrogen & oxygen
The process of splitting wter to release hydrogens and electrons occurs during the process of what?
Electrolysis.
When light strikes chlorophyll molecules they lose electrons which are ultimately replaced by other electrons obtained by?
http://wiki.answers.com/Q/How_are_electrons_lost_by_chlorophyll_molecules_replaced"They are replaced by electrons donated from water molecules which were split by enzymes in the thylakoids inside chloroplasts.
