Question

place the correct words in each sentence to asses your understanding of the cyclic and noncyclic electron pathways of photosynthesis

z Chapter 8 G z Chapter 8 https/ Seved ATP synthase Two types of light reactions occur in called noncyclic, because electron flow can be traced from water to a molecule of of the chloroplast. One is The second type is called cyclic because energized electrons are cyclic passed down an electron transport chain and then returned to their source ATP The electron pathway begins when the pigment complex associated with photosystemabsorbs solar energy, which becomes concentrated hydrogen low energy electrons In this system, however, the are sent down an and eventually returned to the same photosystem, rather than being passed to NADP stroma energized electrons Both photosystems result in a gradent of down their electrochemical gradlent through thylakoid membranes to produce ATP lons, which can flow complexes in the thylakoid membranes The noncyclic electron pathway produces ATP plus reducing power in the form of which is needed for the Calvin cycle. In contrast, the cydlic electron transport chain pathway produces extra other reactions that can be used by the Calvin cycle for NADPH NADP C Prev 11 of 41Next > ype here to sea
