Signal transduction refers to any process by which a cell converts one kind of signal or stimulus into another, most often involving ordered sequences of biochemical reactions inside the cell that are carried out by enzymes and linked through second messengers. In many cases a small initial stimulus is 'amplified' and elicits a large response. This is called a signal cascade.

This episode is about homeostasis, negative feedback and signalling molecules.

This episode looks at the way that the genome controls the activities of the cell by determining the proteins that are built by the cell. The episode also offers some useful biology pick-up lines and a little quiz for fun.
