Learning objectives
- Outline the general characteristics of signal transduction systems.
- Describe the mechanism by which G protein coupled receptors produce secondary messengers.
- Describe the points at which cascades can be regulated by phosphatases and inhibitors.
- Describe phosphatidylinositol-derived second messengers and the functions of \(\ce{Ca2+}\) as a second messenger and the downstream effectors that both activate.
- Describe the characteristics of the receptor tyrosine kinase signaling pathway.
- Describe the signal transduction principles used in regulating glucose levels (pathways initiated by glucagon, epinephrine, and insulin).
- Describe the general processes of cellular apoptosis
- Describe the physiological role of membrane potential in signal transduction.
