During photosynthesis what causes electrons to flow from water to NADP plus?
During photosynthesis, light energy is absorbed by chlorophyll in the thylakoid membrane of the chloroplast. This energy excites electrons in Photosystem II, causing them to flow down an electron transport chain that eventually leads to the reduction of NADP+ to NADPH, along with the generation of ATP.
The transfer of high-energy electrons down the electron transport chain causes what to be transported across the mitochondrial membrane?
The electron movement causes H+ ions to be transported to the cystolic side of the mitochondrial membrane from the mitochondial matrix. This creates the electrochemical gradient that is used to generate chemical energy (ATP from ADP)
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
Energy is transferred from pigment molecule to pigment molecule in the protein complex through resonance energy transfer, leading to excitation of a special chlorophyll a molecule called P680. This excitation of P680 causes the release of an electron, which is then transferred to the primary electron acceptor, initiating the electron transport chain in photosynthesis.
What causes the electrons to become excited and move into the electron transport chain?
Electrons become excited in the electron transport chain due to the energy input from electron carrier molecules like NADH and FADH2. These electron carriers donate the electrons to the proteins in the chain, creating a flow of electrons that drives the production of ATP.
Do all reactions of photosynthesis occur in the chlorophyll?
Yes it has to have sunlight, or imatated sunlight as the light causes the water to split, which is needed by the plant to make food ( c6h12o6) its a long process but yes it needs light. Hence the name PHOTOsynthesis
Why are thylakoids green?
Well thylakoids organize chloraphyll and other pigments within the membrane of the thylakoid. Chloraphyll is a green pigment so that affects the pigment of the thylakoid. I hope that helps .

The photosynthetic electron transport causes the accumulation of protons in which part of the chloroplast?
The accumulation of protons occurs in the thylakoid space within the chloroplast during photosynthetic electron transport. This forms a proton gradient that drives ATP synthesis during the process of photophosphorylation.

What happens in photopigments when they absorb photon energy?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
What substance causes the green colour in plant?
Chlorophyll.
What is the material in plants that causes the green color?
Chlorophyll
What substance in plants causes them to look green?
chlorophyll
What is the end product of noncyclic photophosphorylation?
Cyclic photophosphorylation is the production of some ATP in the light dependent stage of photosynthesis. No photoylsis of water occurs and therefore no reduced NADP is produced either. Only photosystem one is involved here and as light is absorbed by the photosystem, two electrons are released which are accepted by the electron transfer chain. As the electrons are transferred along the chain, energy is released which pumps protons across the thylakoid membrane. A proton gradient forms and the protons diffuse through protein channels associated with ATP synthase enzymes, the proton motive force along with the enzyme combine ADP and inorganic phosphate atom to create ATP. The flow of protons which creates the ATP is chemiosmosis. The ATP can then be used in the light independent stage of photosynthesis or to actively transport potassium ions into the guard cells, so they become turgid as a result of water entering by osmosis. This causes the stomata to open and carbon dioxide can readily diffuse in - increasing the rate of photosynthesis.
