Describe how adenlyl cylases and phospholipase C lead to changes in cell behavior.
Describe how cells turn off activated signaling pathways.
Describe how steroids alter gene expression.
Diagram how receptors activate heterotrimeric GTP-binding proteins.
Diagram how tyrosine kinases recruit proteins to the cell membrane.
Distinguish between paracrine and endocrine signaling.
Given a diagram of a signaling pathway, students should be able to identify ways to manipulate the pathway to increase and decrease the strength of the pathway.
