EVERYDAY SCIENCE

Detailed explanation-1: -Membrane markers allow cells to recognize one another, which is vital for cellular signaling processes that influence tissue and organ formation during early development. This marking function also plays a later role in the “self”-versus-“non-self” distinction of the immune response.

Detailed explanation-2: -Along with peripheral proteins, carbohydrates form specialized sites on the cell surface that allow cells to recognize each other.

Detailed explanation-3: -Recognition proteins: These proteins, called glycoproteins (glyco = sugar) have complex carbohydrates attached to them. These form the identification system that allows your body cells to recognize each other as “self” instead of “invader.”

Detailed explanation-4: -Complex carbohydrates coat the surfaces of cells and have the potential to carry the information necessary for cell-cell recognition. Sugar-specific receptors (lectins) are also present on cells, and can interact with sugars on apposing cells.

Detailed explanation-5: - Marker Proteins-act as the name tag of the cell.
