#Question id: 10254

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?

#Unit 6. System Physiology – Plant
  1. Invertases hydrolyze sucrose in the cell wall, vacuole, or cytosol into its two component hexoses glucose and fructose
  2. sucrose synthase combines sucrose with UDP to produce fructose and UDP-glucose in the cytosol
  3. UDP-glucose pyrophosphorylase then converts UDP-glucose and pyrophosphate (PPi ) into UTP and glucose 6-phosphate
  4. The sucrose synthase reaction is close to equilibrium, the invertase reaction is essentially reversible, driving the flux in the forward direction
