Botany - Respiration in Plants Question with Solution | TestHub

During glycolysis pyruvic acid is produced from glucose and is oxidatively decarboxylated to form acetyl$\mathrm{C}\mathrm{o}\mathrm{A}$. The oxidation of pyruvic acid occurs inside matrix of mitochondria and is called as link reaction. It results in production of$2$molecules of${\mathrm{C}\mathrm{O}}_2$and$2$molecules of${\mathrm{N}\mathrm{A}\mathrm{D}\mathrm{H}}_2$. This acetyl$\mathrm{C}\mathrm{o}\mathrm{A}$is completely oxidised during Krebs' cycle. Thus acetyl$\mathrm{C}\mathrm{o}\mathrm{A}$acts as the linker of glycolysis and Krebs' cycle.
