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 ultimate acceptor of electrons in noncyclic photophosphorylation is NADP+, which receives the electrons to form NADPH. These electrons come from the splitting of water during the light-dependent reactions in photosynthesis.

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.

in the process of respiration,the final acceptor of electrons is molecular oxygen.
The electrons passed to NADPH during noncyclic photophosphorylation are obtained from the splitting of water molecules during the light-dependent reactions of photosynthesis.
In noncyclic photophosphorylation, electrons are excited by light energy and passed along the electron transport chain in the thylakoid membrane of the chloroplast. These electrons eventually end up reducing NADP+ to NADPH, which is utilized in the Calvin cycle for the synthesis of carbohydrates.

When the light cascade finally releases the P680 electrons to the primary electron acceptor of the reaction complex those electrons must be replaced. The plant has an enzyme that preforms photolysis on water, splitting it, so that two electrons are fed one at a time into the p680 chlorophylls as replacement electrons for those they have released to the primary electron acceptor.
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.
If you mean what gas serves as the final acceptor of electrons in the [process of aerobic respiration], the answer is oxygen.
An acceptor atom typically has a negative charge due to its ability to accept an electron pair in a chemical reaction. This negative charge is often balanced by a positive charge on the donor atom.
The acceptor of electrons lost from chlorophyll in chloroplasts is the protein complex called plastoquinone. It is an essential component of the electron transport chain in the thylakoid membrane, where it transfers electrons to other components in the chain to generate ATP and NADPH during photosynthesis.
