In photosynthesis which gets reduced and which gets oxidised in H2O and Co2?

Answer 1

photosynthesis isn't simply one chemical reaction- it's a series of dozens of them.

First step,chlorophyll is reduced. H2O then donates it's electrons to chlorophyll, so H2O is reduced, chlorophyll is oxidized. Then the electrons go to NADP+, an electron shuttle, 2 electrons and a hydrogen, and NADP+ is reduced. then CO2 goes through the calvin cycle, goes through a series of reactions, and out pops Glyceraldehyde-3-phosphate

Answer 2

6CO2 +6H2O---->C6H12O6+ 6O2

C keeps the +4 charge
O goes from -2 to a covalent bond in O2(both in H2O and CO2)
the O in the glucose is sharing with 1 C and 1 H
H goes from +1 to sharing with a O

Reduction is gain of electrons so H gained
Oxidation is loss of electrons so O is oxidized

Answer 3

In gentle reactions, gentle potential is used to oxidixe H2O to O2. The electrons derived variety this oxidation reaction in the gentle reactions are used to shrink NADP to NADPH. The Calvin Cycle oxidizes the gentle-reactions product NADPH to NADP. The electrons derived from this oxidation reaction in the Calvin cycle are used to shrink CO2 to G3P.
