Where do the electrons moving along the inner membrane come from?
Electrons from the Krebs cycle to convert ADP into ATP.
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
Transport chain series of proteins embedded in a membrane along which energized electrons are transported as electrons are passed from molecule energy is released?
Do the electrons moving along the inner membrane of the electron transport chain end up in the matrix?

Where in the mitochondria does the ETC occur?
The electron transport chain (ETC) occurs in the inner mitochondrial membrane. It is comprised of a series of protein complexes embedded in the membrane, through which electrons are passed along to generate ATP.
Is carbon dioxide a photosystem II outputs?
No. Photosystem II outputs are molecular oxygen and protons (H+), along with transformation of ADP to ATP, NADP to NADPH, etc.
Where do the electron get their energy in photosystem 1?
They pass through a series of compounds to photosystem I, losing energy along the way. Photosystem I, like photosystem II, emits high-energy electrons in the light, and the electrons from photosystem II replace these. Photosystem II contains chlorophyll molecules. When a photon (quantum of light) reaches one of these chlorophyll molecules, the light energy activates an electron. This is then passed to the reaction center of the photosystem, where there are two molecules of chlorophyll P680. These pass the electrons to plastoquinone, which, like the chlorophylls, is embedded in the thylakoid membrane. The plastoquinone changes its position within the membrane, and passes the electrons to cytochromes b6 and f. At this stage the electrons part with a significant proportion of their energy, which is used to pump protons (H+) into the thylakoid lumen. These protons will later be used to generate ATP by chemiosmosis. The electrons now pass to plastocyanin, which is outside the membrane on the lumen side. Photosystem I is affected by light in much the same way as photosystem II. Chlorophyll P700 passes an activated electron to ferredoxin, which is in the stroma (the liquid outside the thylakoid). Ferredoxin in turn passes the electrons on, reducing NADP+ to NADPH + H+. Photosystem I accepts electrons from plastocyanin. So, effectively, photosystem II donates electrons to photosystem I, to replace those lost from photosystem I in sunlight. How does photosystem II recover electrons? When it loses an electron, photosystem II becomes an oxidizing agent, and splits water: 2H2O forms 4H+ + 4e- + O2. The electrons return photosystem II to its original state, and the protons add to the H+ concentration in the thylakoid lumen, for later use in chemiosmosis. The oxygen diffuses away.
Electron transport chains help move excited electrons along in photosystem II clusters?
true
Where do electrons moving along the inner membrane move to?
Electrons move around the nucleus of an atom or are exchaned between them. They do not move along membranes
How are the photosynthesis 1 and photosynthesis 2 similar and how they different?
Did you mean Photysystem I and Photosystem II. They both are overall identical except that Photosystem I is actually a later part of the process of Photosynthesis than Photosystem II, its only called Photosystem I because it was discovered first. Photosynthesis starts when light excites Photosystem II causing it to break up H20 that comes from the roots into H2 and 02. (If you are wondering why oxygen becomes two molecules when in H20 there is only one molecule of it, that is because it cannot exist as one molecule stably therefore it bonds with another oxygen from another break down almost instantly.) Then Photosystem II sends electrons across the electron transport pathway (along the membrane of the Thylakoid in between the two photosystems) to Photosystem I which then uses them to convert NaDP+ into NaDPH by adding a phosphate group from outside the Thylakoid. Thats pretty much what each Photosystem does and both are located inside the Thylakoid membrane.

Light excites in photosynthetic pigments?
Light excites two sets of photosynthetic pigments. These are photosystem 1 (PS1) and photosystem 2 (PS2). PS1 is excited by photons at about 700 nanometers, while PS2 is excited at about 680 nanometers.

How does plants absorb solar energy?
Photosystem II takes 680 nm red light and as it absorbs it, particles of different colors resonate and energize chlorophyll a which then retron by being excited. After, the electron gets joined by another one and H+ ions are following along while they get transported through electron trsnaport proteins such as Pq, PC and then go through cytochrome b6f. Then, the sunlight hits Photosystem I at 700 nm red light and the electrons get transferred to the Fq, then it goes through NADP synthase, creating NADPH+ H+. After that, the concentration of H+ ions are excessive in the thylakoid membrane, so ATP synthase shoots out some H+ into the stroma.
