... Mitosis is a process that can be broken down into 4 steps. These steps are called Prophase, Metaphase, Anaphase, and Telophase. A phase called interphase is not actually part of mitosis, but is the resting phase that the cell is in when it is not dividing. Interphase. Most of the time, a cell is not ...

Signal transduction
Signal transduction occurs when an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell. In turn, this receptor triggers a biochemical chain of events inside the cell, creating a response. Depending on the cell, the response alters the cell's metabolism, shape, gene expression, or ability to divide. The signal can be amplified at any step. Thus, one signaling molecule can cause many responses.
