#XL - Q Biochemistry

Sucrose is split into its two monosaccharide units—glucose and fructose—which can readily enter the glycolytic pathway. Two pathways for the splitting of sucrose are known in plants, both of which take part in the use of sucrose from phloem unloading; Invertase pathway and sucrose synthase pathway, some statements are given about these pathways, which of the following is incorrect?
