WebThe Sucrose Loading Mechanism. Assimilates such as sucrose are transported from source to sink through the phloem sieve tubes. It allows for efficient energy transfer and increased energy storage (sucrose is a disaccharide and therefore contains more energy) It is less reactive than glucose as it is a non-reducing sugar and therefore no ... WebApr 13, 2024 · Yeast cells expressing either MeSWEET1a or MeSWEET4 could grow on media supplemented with glucose, fructose and sucrose, suggesting that MeSWEET1a and MeSWEET4 can transport these three types of sugars in yeast, but both demonstrated high transport activity for glucose. MeSWEET2b showed weak activity for glucose transport.

WebAt the source, glucose is produced by photosynthesis and converted to sucrose (sugar), after which it is transported to the various parts of the plant depending on their requirements for glucose. Active transport is then used to transport the sucrose into the sieve tube cells. Phloem hypertonic conditions are created as a result of this treatment.
