Photosystem II is a group of proteins and pigments that work together to absorb light energy and transfer electrons through a

2020-04-07 · 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.

Light Absorption by Photosystem II (PSII) Initiates the Photosynthetic Pathway. 2. Electron Transport Through the Cytochrome Complex Generates a Proton This reaction splits a water molecule into two hydrogen ions and an oxygen atom, which immediately combines with another oxygen atom to form O2. This splitting Together, this ATP and the NADPH provide energy to drive the light-independent Calvin Cycle, which fixes carbon from CO2 in organic compounds.

1. there are two types, Photosystem I and Photosystem II 2. antenna complexes are highly organized arrangements of pigments, proteins, and other molecules that capture light energy 3. energy is transferred to a reaction center where electrons are actually moved into electron transport chains 2017-12-12 we've seen in previous videos that photosynthesis can be broken down into the light dependent reactions and the Calvin cycle and the light dependent reactions is where we take light as an input along with water and we'll see the water is actually a source of electrons and we can use that to store energy in the form of ATP and NADPH and as a by-product we produce molecular oxygen which is very 1.
