Connecting Concepts: Animal Physiology/Signal Transduction 2: Intracellular Signal Transduction

Students dive into signal transduction with a journey into the olfactory neuron of a mosquito. They look at how lactic acid in human sweat triggers a cellular and behavioral mosquito response. Students: 1) step through an animation of the pathway; 2) reconstruct the sequence of events in the pathway; and 3) conduct simulated experiments testing chemical inhibitors of the pathway and the behavior of mosquitoes with mutations in the pathway; and 4) identify molecular amplification and regulatory events.

Part two of three excellent interactive exercises that investigate the concept of signal transduction. Students are required to draw conclusions from information and data provided. This is a very difficult concept for students. Very well organized and well written. Have used in class successfully.
