Botany - Respiration in Plants Question with Solution | TestHub

When 3-phosphoglyceraldehyde is converted into 1,3 diphosphoglyceric acid, two electrons and two protons are released which are utilised to convert ${\mathrm{NAD}}^{+}$to $\mathrm{NADH}$. $${\mathrm{NAD}}^{+}+2{\mathrm{H}}^{+}+2{\mathrm{e}}^{-}\to \mathrm{NADH}+{\mathrm{H}}^{+}$$ Related Theory Glycolysis is a partial breakdown of a sixcarbon glucose molecule into two, threecarbon molecules of pyruvate, $2\mathrm{NADH},2{\mathrm{H}}^{+}$, and 2 net ATP as a result of substrate-level phosphorylation. Glycolysis occurs in the cytoplasm of the cell.
