What is the mechanism for protein-based hormones to work?
What is the mechanism for protein-based hormones to work?
- They rely on the receptor to produce second messengers
- They activate the 2nd messenger system (correct)
- They bind on the inside of the cell
- They do not have a specific mechanism
Why are the second messengers called '2nd messengers'?
Why are the second messengers called '2nd messengers'?
- Because the hormone is the 1st messenger (correct)
- Because they bind on the outside of the cell
- Because they activate the receptor
- Because they are released by the hormone
What happens when protein-based hormones bind on the outside of the cell?

- They release second messengers
- They produce steroid-based hormones
- They enter the cell immediately
- They activate the receptor (correct)
