18.

Antigen can be defined as any foreign substance that can produce immune responses in the host body. It induces the production of antibodies. Antigens are usually proteins present on the surface of cells, viruses, bacteria, fungi. Antigens also can be polysacccharides or lipids.

Fungal spore, viral spike protein, bacterial flagella, bacterial cell surface transport protein all are antigens.

A glucose molecules is not an example of antigen.

A glucose molecule is the answer.
