Wolf and Elk Populations. This reaction splits water into two hydrogen ions and an oxygen atom that combines with another oxygen atom to form O2. It is responsible for the presence of oxygen biloogy our atmosphere.
Only chlorophyll a participates directly in the light reaction, but accessory photosynthetic pigments absorb light and transfer energy to chlorophyll a. ATP from the light biolog also powers parts of the Calvin cycle. Org web experience team, please use our contact form. The reaction is as follows:. A specialized molecule sharing the reaction center with the chlorophyll a molecule; it accepts an electron from the chlorophyll a molecule.There's a lot of carbon in your body - in DNA, proteins, carbohydrates, fats, and other key biological molecules. How did that carbon get there? Drumroll. Photosynthesis explained, step-by-step. PLEASE note: for the first thirty seconds or so, I have Photosystem II. Crash Course Biology is now available on DVD! . I just started revising Photosynthesis for my AP Bio exam.
