1.What is the difference in the end products of photosynthesisin plants purple bacteria,and green-sulfur bacteria?

2.The herbacide atrazine binds to the quinone-binding site ofphotosystem II and blocks the formation of plastoquinon. Whateffect would atrazine have on a) O2production b)ATP productionc)NADPH production

3.Calculate the free energy change for the light dependantreaction of photosynthesis in plants.How many moles of ATP couldtheoretically be synthasized using this energy?

4. Some green sulfur bacteria produce NADH as a result of lightobsorption. This process requires H2S as an electron donor. Write abalanced equation for the light-dependant reactions forphotosynthesis in these bacteria.

i know the light dependant reaction is 2H2O + 2NADP+ + 3ADP +3Pi → O2 + 2NADPH + 3ATP so would you just add H2s onto the reagantside and you will have NADP+ on product side
