Lesson Objective

Predict the downstream effects of mutations or chemical disruptions to any component of a given signal transduction pathway.

What happens to a biological system when a component of a signaling pathway is mutated, blocked, or structurally altered?

How do external chemicals (like medications, poisons, or toxins) interfere with cellular communication?

4.3-Signal Transduction Pathways

The purpose is to analyze what happens when cell communication systems break down due to genetic mutations or external chemicals.
