Question

ATP and NADPH production Place the correct word(s) in each sentence to assess your understanding of the cyclic and noncyclic electron pathways of photosynthesis hydrogen oxygen glucose ATP water electron acceptor electron transport NADPH ATP synthase chain energized noncyclic reaction center hydrogen acceptor NADP NAD cyclic Two types of light reactions occur in thylakoid membranes. In the electron flow can be traced from water to a molecule of electron pathway, the electron In the pathway, energized electrons are passed down an electron transport chain and then returned to their source. The noncyclic electron pathway uses two photosystems, called photosystem I and photosystem II. A photosystem consists of a pigment complex and anwithin the thylakoid membrane. In the noncydlic electron pathway, the pigment complex associated with photosyatem becomes concentrated in a first absorbs solar energy, which Energized electrons then escape to a nearby electron acceptor, followed by replacement of these electrons provided by the spatirgof_ This process also releases to the atmosphere. The cyclic electron pathway begins when the pigment complex associated with photosystem absorbs solar energy, which becomes concentrated. In this system however, the down an are sent and eventually returned to the same photosystem. Both photosystems result in a gradient of gradient through ions, which can flow down their electrochemical complexes in the thylakoid membranes to produce ATP The noncyclic electron pathway produces ATP plus reducing power in the form of needed for the Calvin cyole. In contrast, the cyclic pathway produces extra by the Calvin cycle or for other reactions -, which is that can be used
