Signal Transduction Pathways

Mr. Anderson explains signal transduction pathways using an analogy of a guitar. He describes how chemical messages are transduced into cellular actions, often involving phosphorylation cascades. The video provides a detailed example using a G protein receptor and explains how epinephrine affects liver cells. An animation illustrates the process, and the video concludes with a review of key concepts.
