DA 8 1) Major steps in photosynthesis Photosystem II Photosystem I ATP Synthase Calvin Cycle 2) Does this step depend on any Our observations suggest that photodamage to PSII occurs in two steps. Step 1 is the light-induced inactivation of the oxygen-evolving complex. Step 2, occurring after step 1 is complete, is the inactivation of the PSII reaction center by light absorbed by chlorophyll. Abstract.

Photosystem 2 steps

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.

Artificial Photosynthesis: From Basic Biology to Industrial

Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water and transport it to the leaves through the stem. Step 3. As sunlight falls on the leaf surface, the chlorophyll, i.e., the green pigment present in the plant leaf, traps the energy in it.

These electrons are used in several ways. 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.

When the antenna complex transmits resonance energy to the reaction center, where the electron acceptor comes into play.

This pathway occurs in the thylakoid membranes and requires participation of two light-gathering units: photosystem I (PS I) and photosystem II (PS II). · 2. · 3. · 4. The light-dependent steps of photosynthesis are the formation of high-energy chemical These two photosystems work in series, first PS II and the PS I.
