| slower, longer | The endocrine system affects the body (faster/slower) than the nervous system and (short/long)-er lasting. |
| receptors | All hormones act by binding these proteins. |
| endocrine | What system regulates the metabolic activities? |
| peptide hormones, steroid hormones, tyrosine derivatives | What are the three basic types of hormone chemistry? |
| peptide hormone | They are made in the rough ER and are water soluble. They are hormones and made of peptides and bind to a membrane-bound receptor. |
| effector | The target cell of the hormone. |
| intracellular second messenger | A hormone may activate one of these, such as cAMP or cGMP. |

| thyroxine | ... |
| epinephrine | ... |
| norpinephrine | catecholamine with multiple roles including as a hormone and a neurotransmitter. Areas of the body that produce or are affected by this are described as noradrenergic. |
