Document Summary

To understand the evolutionary aspects of cell communication. Cells have a limited amount of receptors on their surface therefore restricting the types of signals they can respond to. There are 2 types of complexity in the control of cell behaviour: one signal molecule binding to one receptor can cause a multitude of different effects. A cell receiving many signals can cause a summation effect where the additive effect of several signals can collectively generate a response. The same signal molecule can induce different responses in different target cells. Lack of signals for a cell can lead to apoptosis. To be familiar with the basic intracellular signalling pathways. Signal transduction: process where one type of signal is converted to another. Signal transduction begins when a receptor protein on the target cell receives an incoming extracellular signal and converts it to the intracellular signals that alter the cell behaviour. To know the different types of communication/signalling mechanisms and their characteristics.
