1. Show how a steroid hormone causes change in a target cell.
2. Show how Thyroxine (T4) causes a change in a target cell.
3. Show how Norepinephrine causes a change in a target cell using both Adenylate Cyclase and Phospholipase C
4. Show how insulin causes a GLUT 4 transporter to move in to the cell membrane so that glucose from the blood may be uptaken into the cell. (Hint: use tyrosine kinase and autophosphorylation).

Diagrams with explanations are best
