A Level Biology Revision (Year 13) "Adrenaline and Cell Signalling"

In this video, we look at adrenaline and cell signalling. We explore the roles of the enzyme adenylyl cyclase and the role of cyclic AMP as a second messenger. We then look at how this triggers glycogenolysis via protein kinase enzymes. Image credits: Fight or flight response https://commons.wikimedia.org/wiki/Fi...
