State 2 molecules that get reduced and 2 that get oxidized during photosynthesis. 
----------------------------------

I know that NADPH and Glucose are in their reduced form. 

2 molecules that get reduced. Will it be NADP+ because it is gaining 2 electrons and H+ to form NADPH? I'm not sure what else.. 

2 molecules that get oxidized. Will it be NADPH because it is loosing electrons to form NADPH? And water because it is loosing electrons which are carried into photosystem 2 and electron transport all the way to photosystem 1 To NADP+ reductase and etc. 

Please help clarify this. I'm confused

    6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

    Biological energy is frequently stored and released by means of redox reactions. Photosynthesis involves the reduction of carbon dioxide into sugars and the oxidation of water into molecular oxygen. The reverse reaction, respiration, oxidizes sugars to produce carbon dioxide and water. As intermediate steps, the reduced carbon compounds are used to reduce nicotinamide adenine dinucleotide (NAD+) to NADH, which then contributes to the creation of a proton gradient, which drives the synthesis of adenosine triphosphate (ATP) and is maintained by the reduction of oxygen. In animal cells, mitochondria perform similar functions.
