Which protein complex in the electron transport chain after photosystem 2 produce atp

Enzyme NADP reductase enzyme in the chain takes 2 electrons, 1 from the previous protein and 1 from a hydrogen to make NADPH. 9. Photosystem II replaces its lost electron by splitting water in photosynthesis into 2 electrons, 2 hydrogen ions, and water.The electron transport chain of photosynthesis is initiated by absorption of light by photosystem II (P68o). When P680 absorbs light, it is excited and its electrons are transferred to an electron acceptor molecule. Therefore, P680 becomes a strong oxidising agent, which protein complex in the electron transport chain after photosystem 2 produce atp

1. pigment molecule absorbs photon of light, passing its energy to other pigment molecules until it reaches photosystem 2 where it excites an e of chlorophyll P680 to a higher energy level. 2. e is captured by primary e acceptor.

Which protein complex in the electron transport chain after photosystem 2 produce atp free

The electron transport chain (ETC) is conducted in the mitochondria. The four complexes of the ETC, along with the enzyme that produces ATP (known as Complex V, ATP synthase, or F0F1ATPase), are

Photosynthesis. Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O 2 from H 2 O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.

Schematic models for the major protein complexes involved in photosynthesis. ATP synthase is a protontranslocating ATP hydrolase. Photosynthetic electron transport establishes a transmembrane gradient of proton concentration, a proton motive force, that serves

Which protein complex in the electron transport chain after photosystem 2 produces ATP? the water splitting enzyme What happens to the light energy that is trapped by chloroplast during the first

Mar 19, 2019 Photosystem II or PS II is the protein complex that absorbs light energy, involving P680, chlorophyll and accessory pigments and transfer electrons from water to plastoquinone and thus works in dissociation of water molecules and produces protons (H) and O2. Location: It is located on the outer surface of the thylakoid membrane.

Complex 2 is a parallel electron transport pathway to complex 1, but unlike complex 1, no protons are transported to the intermembrane space in this pathway. Therefore, the pathway through complex 2 contributes less energy to the overall electron transport chain process.

The First Steps of Cellular Respiration. Pyruvate is further oxidized in the Krebs cycle producing two more molecules of ATP, as well as NADH and FADH 2 molecules. Electrons from NADH and FADH 2 are transferred to the third step of cellular respiration, the electron transport chain.
