Best Answer

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.

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.

How do fatty acid molecules differ from amino acid molecule?

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