The non-reducing sugar sucrose is most commonly translocated in the phloem rather than reducing sugar. Why?
a.) because they are less reactive than their reducing counterparts
b.) because sucrose contains more energy than a monosaccharides
c.) because the ketone or aldehyde group is reduced to an alcohol or combined with a similar group on another sugar so as not to be oxidized 
Which one of the following statements is true about translocation of non-reducing sugar?

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?
