what are the final electron acceptors for the electron transport chains in light reactions?
nadph
section::::function and chemistry.:photosynthesis.:light reactions.:nadp reduction.









































electrons are often removed from the electron transport chains to charge nadp with electrons, reducing it to nadph. like atp synthase, ferredoxin-nadp reductase, the enzyme that reduces nadp, releases the nadph it makes into the stroma, right where it is needed for the dark reactions.









































because nadp reduction removes electrons from the electron transport chains, they must be replaced—the job of photosystem ii, which splits water molecules (ho) to obtain the electrons from its hydrogen atoms.

individual bacteria use multiple electron transport chains, often simultaneously. bacteria can use a number of different electron donors, a number of different dehydrogenases, a number of different oxidases and reductases, and a number of different electron acceptors. for example, "e. coli" (when growing aerobically using glucose as an energy source) uses two different nadh dehydrogenases and two different quinol oxidases, for a total of four different electron transport chains operating simultaneously.
