Photosystem II is the first step of photosynthesis, where the chlorophyll molecule uses light energy to take an electron from a water molecule. This splits the water molecule, generating oxygen and hydrogen ions. The electrons and hydrogen ions are used to power the creation of ATP, and ultimately carbohydrates, in later stages of photosynthesis. Step 1 Step 2 The leaf of a plant needs sunlight to make energy.

Later, photosystem II was discovered and found to be earlier in the electron transport chain. But it was too late, the name stuck.

feeds excited electrons to an electron transport chain. what is the first step in photo 2? When the antenna complex transmits resonance energy to the reaction center, where the electron acceptor comes into play.

Describe the second step of the electron transport steps that occurs in photosystem 2. electron leaves chlorophyll a and goes to the primary electron acceptor.

Light energy (indicated by wavy arrows) absorbed by photosystem II causes the formation of high-energy electrons, which are transferred along a series of acceptor molecules in an electron transport chain to photosystem I. Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms.

A 700 and carotenoids. Photosystem 2: PS 2 contains chlorophyll B, chlorophyll A Photosystem I is one of two photosystems in the photosynthetic light reactions of algae, plants, and cyanobacteria. Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH. The combined action of the entire photosynthetic electron transport chain in the last video we learned a little bit about both photosynthesis it and we know in very general terms it's the process where we start off with photons and water and carbon dioxide and we use that energy and the photons to fix the carbon and now there's this idea of carbon fixation is essentially taking carbon in a gaseous form in this case carbon dioxide and fixing it into a solid structure Photosystem II (PSII) catalyses the photoinduced oxygen evolution and, by producing reducing equivalents drives, in concert with PSI, the conversion of carbon dioxide to sugars.

First, when the electrons are removed, the water molecule is broken into oxygen gas, which bubbles away, and hydrogen ions, which are used to power ATP synthesis.
