Cytokines are proteinaceous substances that are secreted by specific immune system cells. These belong to a category of signaling molecules that are helpful in communication between the cells of immune system and thus help to mediate and regulate immunity, inflammation and hematopoiesis. Cytokines have ability to act on three types of cells -
- The cell that secretes them
- The nearby cells
- The distant cells
These molecules bind to the receptors present on the responsive target cell and evoke a particular biological activity.

Glycolysis. In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule.
An eye contains receptors called photoreceptors viz rod and cone cells. Cones are cone-shaped structures and are necessary for daylight vision. Unlike cones, rods are rod-like structures and are necessary for dim-light vision. Rods are far more numerous than cone cells.
