H.1.2 - State that hormones can be steroids, proteins and tyrosine derivatives, with one

example of eachHormone Type: Example: One Effect of hormone:

H.1.3 – Distinguish between the mode of action of steroid hormones and protein hormones

Steroid Hormones:

Steroid Hormone

Goes to the ___________________. Then it binds to the receptor and becomes the ________________. It then passes through __________________and selectively binds to ___________________ and now it can ________________________.

Protein Hormones :

Protein Hormone

Goes to the ___________________. Then it binds to the receptor which is on the _______________ of the cell membrane.The receptor sends a __________________ which goes through the

cell membrane and sends the message to the gene. now it can ___________________________.
