After electrons leave photosystem ii, they go into an electron transport chain of three protein complexes. where do they go after that electron transport chain?

The right answer is photosystem I

And the three protein complexes are : plastoquinone, cytochrome b6f complex, plastocyanin.

In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:

H2O ==> photosystem II (which contains P680) ==> plastoquinone ==> cytochrome b6f complex ==> plastocyanin → photosystem I (which contains P700) ==> ferredoxin ==> ferredoxin-NADP + reductase ==> NADP +

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.

actually the answer is c
