Helps regulate growth and trigger sexual maturity
How to water soluble hormones activate a cell
Receptors on target cells outside of membranes for hormones to attach to
How to lipid soluble hormones activate something in a cell
Receptor proteins are inside target cell as hormones can diffuse across membrane
How does a hormone effect a target cell
Increases or decreases some of its functions
How does the pancreas work
Controls blood sugar by releasing insulin or glucagon
What happens to your pancreas when your blood glucose concentration increases
Beta cells release insulin which lowers blood sugar by increasing rate of cells storing sugar as glycogen or fat
