Electrons that enter the light reactions of photosynthesis c

Electrons that enter the light reactions of photosynthesis can be traced through all the photosynthesis processes ending up in a molecule that can be later used in respiration. These same electrons can then be tracked through the processes of respiration. Put the below options in order starting with which molecule the electrons originally come from (at the beginning of photosynthesis) and ending with the molecule on which they ultimately end up (at the end of respiration). You will need to use 7 of the options ONCE and 1 of the options TWO times. You will not use 2 of the options. Options: NADPH, NADH, PS II, G3P, H2O, O2, Complex 1, PS 1, Ubiquinol (Q), and CO2

Solution

NADPH....always there is a continuous flow of electrons from the water to NADPH and it leads to release of energy. This energy has been used in carbon fixation. NADH PS II..........PSII gets the electron from the water, H2O....third step G3P...........sugar of calvin cycle H2O...........electrons from water are excited, water gives electrons to start the path........gives H+ and o2...this is the first step O2...........O-2 ions formed from the water after removed of electrons,combine, form diatomic O2... is the second step. Complex 1 PS 1....the electron gets passed from the PSII to PSI through a series of steps. Ubiquinol (Q).............quinone pool could be observed in photosynthetic microorganisms CO2...carbon fixing reactions or dark reaction or light independednt reactions shows entry of 6 molecules of carbon dioxide into the calvin cycle and produces glucose, G-3-P. Total 9 options 7 of the options ONCE and 1 of the options TWO times. H2O--->O2----->PSII------->Quinone pool--------> O2-------->PSI--------------->CO2----------> NADPH------>G3P
