WebThe Q y (S 1 ) excitonic structure, excitation energy transfer (EET), and primary charge separation rates of the isolated D 1 / D 2 -cyt b 559 photosystem II (PS II) reaction center (RC) have been the subjects of many frequency and time domain spectroscopic studies since its isolation from spinach in 1987 (for a recent review see Dekker and van … WebAnswer: A chloroplast contains chlorophyll, a green pigment. A chloroplast can also contain carotenoids, yellow-orange pigments which are not visible until the chlorophyll is gone. Chloroplast is the specific name for a type of plastid. Chromoplasts contain other pigments, such as yellow, red and... iowa vs northwestern football score

WebA. Photosystem I passes electrons on to Photosystem II. B. Each photosystem contains numerous pigment molecules that act as antennas to capture light. C. Photosystem II contains a reaction center molecule that loses electrons which are then replaced by electrons from water. D. Electrons in the reaction center molecule are excited by … WebFeb 23, 2024 · Summary. Chlorophyll is a pigment that gives many plants their green color, and it may offer various health benefits. However, there is little evidence to support these claims. When taken as a supplement, chlorophyll may cause green stools, stomach cramps, loose stools, and other gastrointestinal side effects. 3. WebMay 25, 2024 · Photosystem I was discovered first. Later, photosystem II was discovered and found to be earlier in the electron transport chain. But it was too late, the name stuck. Electrons first travel through photosystem II and then photosystem I. The Electron Transport Chain. While at photosystem II and I, the electrons gather energy from … iowa vs northwestern odds
