Facilitated diffusion in Glucose. Glucose is a six-carbon sugar that provides energy needed by cells. Since glucose is a large molecule, it is difficult to be transported across the membrane through passive diffusion Hence, it diffuses across membranes through facilitated diffusion, down the concentration gradient.

Facilitated diffusion is a type of passive transport that allows molecules to move across cell membranes from areas of higher concentration to areas of lower concentration with the help of specific transport proteins. The main significance of facilitated diffusion is the absorption of certain molecules in the body, such as fructose and nucleotides in the small intestine.

Explanation:
Facilitated diffusion is a form of passive transport, meaning that it does not require the input of energy to move molecules across a cell membrane. Instead, facilitated diffusion relies on specific transport proteins that help molecules move across the membrane.

In the case of fructose and nucleotides, these molecules are too large and complex to move across the membrane through simple diffusion. Instead, they bind to specific transport proteins in the cell membrane, which then change shape and carry the molecules across the membrane to the other side.

This process is important for the absorption of nutrients in the body. Fructose is a type of sugar found in fruits and honey, and it is an important source of energy for the body. Nucleotides are the building blocks of DNA and RNA, which are essential for the growth and replication of cells.

Facilitated diffusion is also important for the absorption of other nutrients in the body, such as amino acids, which are absorbed in the gut, and mineral ions, which are absorbed by plant roots.

In contrast to active transport, which requires the input of energy to move molecules against their concentration gradient, facilitated diffusion allows molecules to move down their concentration gradient, from areas of higher concentration to areas of lower concentration, without the need for energy.

Overall, facilitated diffusion is an important mechanism for the absorption of nutrients in the body, and it allows certain molecules to cross the cell membrane efficiently and effectively.
