What causes the electrons to become excited and move into the electron transport chain?
In photosynthesis, the electrons from the chlorophyll are excited by the sunlight
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)
What is the difference between photosynthesis I and photosynthesis II?
Photosynthesis II or PS II (photosystem II) comes before PS I. PSII uses a pair of P680 chlorophyll a, while PSI uses a pair of P700 chlorophyll a. These systems populate the thylakoid membrane.First, light hits PS II and excites its pigment molecules and the energy bounces off the pigment molecules until it gets to the P680 chlorophyll and excites its electrons which then causes it to give off an electron to the Primary electron acceptor.Now the pair of P680 is deprived of an electron, this is where water comes nto play. An enzyme catalyzes the splitting of water to produce O2 and two electrons, these electrons supply the ones that the pair of P680 chlorophyll gave away, this enables the P680 to be able to get excited again and again without being deprived of electrons.Back to the primary acceptor, the excited electron passes from PS II to PS I via the Electron Transport chain. This produces ATP.The electron then is at the P700 pair of chlorophyll a's of PS I which excites it and it gives off that electron to another primary electron acceptor which transports its electrons via ETC as well, but the final electron acceptor is NADP+, which with the electron becomes: NADPH.
What is the structure in a plant that produce chlorophyll?
The structure in a plant that produces chlorophyll is the chloroplast. The chlorophyll causes the plant to turn green.
Why does the pH of the cell become more basic during photosynthesis?
During the light reactions of photosynthesis, protons (H+) are ferried into the thylakoid space using the energy from the excited electrons in Photosystems 680 and 700. H+ causes buildup of hydronium (H3O+) ions in water, which are acidic.
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?
internal thylakoid space

A series of molecules found in the inner membranes of mitochondria and chloroplasts through which electron pass in a process that causes protons to build up on one side of the membrane?
i belive it is electron transport chain

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.

Chlorophyll.
