Chlorophyll special pair
WebThe phytyl tails of the chlorophylls and pheophytins have been removed for clarity. The side chains of Y Z (D1-Tyr161) and D1-His190 are shown in yellow and Y D (D2-Tyr160) and D2-His189 in orange. The four chlorophylls comprising P680 are in direct van der Waals contact, and other electron transfer distances are given in angstroms. WebChoose one: A. The concentration of ATP is much lower than the concentrations of its hydrolysis products, ADP and Pi. B. ATP is much higher in concentration than the products ADP and Pi. C. Cells use enzymes to perform these reactions, resulting in a difference between ΔG° and ΔG. D.

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.
