Biology: Overview of cell signaling

Overview of cell signaling. Autocrine, paracrine and endocrine signaling.

Biology

Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important. Covers topics seen in a high school or first-year college biology course.

Cell signaling

If you were a cell, how would you say hello to your neighbor? Well, okay, you probably wouldn't be saying hello. (Maybe something more like "Divide now!" or "Become a skin cell!") Whatever you might be saying, however, chances are you'd be saying it in the form of chemical signals. Learn more about the types of signaling molecules cells use, the receptors that perceive them, and the types of changes they produce inside of the cell.
