Detailed explanation-1: -Glyceraldehyde phosphate is oxidised in glycolysis.
Detailed explanation-2: -We saw PGAL as a major component of the Calvin-Benson cycle. * Oxidation of PGAL (2) provides the energy to add a second phosphate, while creating a 2 molecules of NADH. It is the addition of this phosphate which provides the excess ATP yield of the pathway.
Detailed explanation-3: -Glucose gets oxidized during glycolysis.
Detailed explanation-4: -NAD+ is the oxidized form of the molecule; NADH is the reduced form of the molecule after it has accepted two electrons and a proton (which together are the equivalent of a hydrogen atom with an extra electron).
Detailed explanation-5: -So, PGAL is formed by the addition of H2 atom and hence this reaction is called as a reduction reaction.
