1. Sugar (sucrose) cannot penetrate the cells and cannot be absorbed in blood because this disaccharide molecule is too big.
2. After the degradation of the disaccharide to monosaccharides (fructose, glucose, etc.) with the help of the enzyme sucrase these monosaccharides are easily absorbed in blood.
3. The monosaccharides molecules can penetrate by diffusion.
This process is facilitated diffusion.
sugar molecules enter a cell because of the cell membrane that you can see in the outer membrane of the cell.It can enter a simple sugar which is fatty acid.

Nuclear decide and allow which molecules will be enter in the cell,- Isrg Rajan
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
Exocytosis is the process by which large molecules are transported out of the cell.

the receptors on the protein carrier recognise glucose allowing it to enter the cell :)

hormones such as insulin opens up channel proteins which are like doors to a cell. Channel proteins allow larger molecules, such as sugar, to enter the cell.

amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.
