Cell Signaling – Comprehensive Unit Plan
Cell signaling is the process by which cells communicate with each other and respond to external stimuli, ensuring the coordination of vital biological functions. This system involves a signal binding to a receptor on a target cell, and triggering a series of intracellular events. These signaling pathways often include second messengers, protein kinases, and phosphorylation…

How is Glucose Taken Up by Cells?
This worksheet takes a closer look at the cell membrane and how insulin binds to the receptor on the cell membrane which creates a signal cascade, resulting in the movement of the Glut-4 transport protein to the surface of the cell. Students interpret a graphic showing the membrane, receptors, and the Glut-4 transport protein.

Investigation: Taste Buds and Signal Transduction
As a part of the chapter on cell signal pathways, students perform a lab that examines how their taste buds are affected by Gymnema. For this lab, I simply placed a question on the board “How does Gymnema tea affect your ability to taste sweet foods?” I provided them with a list of…
