harnesses light energy into electrons

Question 21

what do the electrons do after being carried to etc in photosystem 2?

Answer 21

splitting of water replaces e-, releases H+ to thylakoid,and releases O2

Question 22

ETC

Answer 22

e- drops off energy moving through the ETC

do H+ ions get pumped from low to high, or high to low?

Answer 23

low to high

Question 24

how can H+ get passes back through?

Answer 24

ATP synthase

Question 25

photosystem 1

Answer 25

e- are reenergized by sunlight and then 2 are added to NADP+ along with a H+ making NADPH
