Intro Endocrine Physiology
Identify the movements associated with the following hormones:
1. Growth hormone
1. AAs into cells
2. Glucose into cells
3. Glucose out of cells
4. Reabsorption of water
What are the classes of hormones?
Protein-peptide hormones (prolactin, ADH...)
Amine hormones (Epinephtine, norepinephrine)
Iodothyronines (T4, T3)
Steroid hormones (Androgens, estrogens, cortisol...)
How are amine, iodothyronines, and steroid hormones synthesized?
Which hormone types require carrier proteins?
3 classes of hormone receptors
G-protein coupled receptors
Protein tyrosine kinases
Ligand-gated ion channels
What is the mechanism of steroid hormone action?
Receptor-hormone dimers form
Bind at chromatin to express or repress a gene
What is the mechanism of thyroid hormone action?
T4 activated to T3
Regulates expression of DNA
