WebDRAW a curved arrow mechanism for photosynthesis with the following steps. Show the flow of electrons in the drawing. 1: Absorption of sunlight and excitation of chlorophyll molecules. 2: Transfer of energy to reaction center chlorophylls, which lose an electron and become oxidized. 3: Electron transfer from oxidized chlorophylls to an electron WebCyanobacteria can have a dramatic effect on the quality of water used for human activities, as reported by the World Health Organization. Remote sensing is an appropriate tool for continuous monitoring of the entire water body, given the current state of the lake. In the present study, surface water quality was evaluated using multi-temporal sentinel-2 …

WebThe reaction center of a photosystem contains a unique pair of chlorophyll a molecules, often called special pair (actual scientific name—that's how special it is!). Once … WebThe reaction center pigments of PS II are called P680, which are able to absorb light with the wavelength of 680 nm (Figure. 4). In addition, The PS I core complex consists of reaction center pigments P700, of which the maximum absorption wavelength is 700 nm.
WebThe reaction center contains a pair of chlorophyll a molecules with a special property. Those two chlorophylls can undergo oxidation upon excitation; they can actually give up an electron in a process called a photoact. It is at this step in the reaction center, that light energy is converted into an excited electron. http://photobiology.info/Yocum-PRC.html
