Answer 1

Role	Action	Location in chloroplast
Photosystems 1 and 2	Photosystem1- NADPH Synthesis. Photosystem 2- hydrolysis of water and ATP Synthesis.	Photosystem1- outer surface of thylakoid membrane. Photosystem 2-inner surface of thylakoid membrane.
Cytochrome b​​​​​​6​​​​​f	transfer of electons between two photosynthetic reaction.	Thylakoid membrane.
Ferredoxin NADP reductase (FNR)	catalyse electron transfer between ferredoxin and NADPH.	Found in soluble stroma,atta atta to stroma thylakoids as well as inner envelope membrane.
ATP Synthase	catalyses ATP Synthesis.	Thylakoid membrane.
Plastoquinone Qb	electron transporters.	Thylakoid membrane.
Plastocyanin	electron transporters.	Lumen of thylakoid.
Ferredoxin	electron transporters.	Stroma thylakoids.
Photons	deliver kinetic energy to atoms.
Protons	electron transporters.	thylakoid lumen.
Water	photolysis.
Oxygen	for respiration of plants.
NADP+	provide energy to many reactions in cell.	Stroma
NADPH	electron transporters.	Stroma
ADP+ Pi	formation of energy currency.	Thylakoid membrane.
ATP	energy formation.	Thylakoid membrane.
