Answer #1

1. The overall reaction occurs in light reaction is

2H2O + 2 NADP+ + 3 ADP + 3Pi  1585682123773_image.pngO2 + 2NADPH + 3 ATP

the other way to write the reaction of electron transport chain is

H2O1585682253308_image.pngPS II 1585682271434_image.pngPlastoquinone 1585682290295_image.pngCyt b6 f 1585682309495_image.pngPlastocyanin 1585682324812_image.png PS I 1585682334129_image.png NADPH

2. The high energy unstable electron is transferred from one pigment to other pigment creating a chain of redox reactions.

3. The reaction is from Calvin cycle. the factors responsible for the production of 3-Phosphoglycerate are Ribulose-1,4-bisphosphate, 3 CO2 and 3 H2O. The enzyme catalyzes the reaction is Ribulose -1,5-bisphosphate carboxylase/oxygenase (RuBisCo). later 6 ATP will convert into 6 ADP and 6 NADPH/H+ will convert into 6 NADP+ & 6 Pi molecules.
