Real Life Application of Signal Transduction Pathways

This video shares very interesting effects of the Signal Transduction Pathway. It really helps to see how the molecular events in our cells can translate into major medical events....

G-Protein Role in Signal Transduction

"G-protein coupled receptors convert extracellular hormonal signals into intracellular second messengers that produce a physiological response in the target cell" - L. Keeley

What is the second messenger in this video? What is the end result (cellular response) after the initial signal?

Explanation of the Signal Transduction Pathway

Here is an excellent explanation of the role of Cyclic AMP.




What is the meaning of Protein Kinase? What is it's role inside of the cell?

How Do Cell Communicate?

Can you explain everything that you just watched in this film? How relevant is this to your textbook details? What is the Signal Transduction Pathway? What are the names of some of the proteins involved?
