The energized electrons are quickly absorbed by an electron acceptor called “____” embedded in the ____________________ membrane
The electrons lost by the chlorophyll A molecule in the reaction center of the Photosystem II are immediately ___________________ with two electrons released in the _____________________ or splitting of one molecule of water
In addition to the two electrons, photolysis also produces two _______ and _______ that is released in to the atmosphere
The two electrons from Photosystem II that were absorbed by electron acceptor “Q” are then transferred to ___________________ and on to several other molecules in a series of ___________________________ reactions
This electron transport chain is very similar to that found in mitochondria
The production of ATP is similar to that in _______________________ in that H+ are pumped into the ______________________ and large electrochemical gradient is established.

The energized electrons are quickly absorbed by an electron acceptor called “plastoquinone” embedded in the thylakoid membrane

The electrons lost by the chlorophyll A molecule in the reaction center of the Photosystem II are immediately _____ with two electrons released in the _____________________ or splitting of one molecule of water

Not sure what to add here... I know that photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.

In addition to the two electrons, photolysis also produces two hydrogen ions and oxygen that is released in to the atmosphere

The two electrons from Photosystem II that were absorbed by electron acceptor “Q” are then transferred to cytochrome and on to several other molecules in a series of REDOX reactions

This electron transport chain is very similar to that found in mitochondria
The production of ATP is similar to that in mitochondia in that H+ are pumped into the thylakoid interior (lumen) and large electrochemical gradient is established.
