Function of Luteinizing Hormone in females
Stimulates ovulation & progesterone production
Function of Antidiuretic hormone
is released when the blood becomes too concentrated
Function of Luteinizing hormone in males
stimulates testosterone production in the testes
Describe the difference in how steroid hormones and peptide hormones elicit their effects
- Steroid hormones pass directly across plasma membranes & nuclear membranes to turn on genes
- Peptide hormones are first messenger that binds to a hormone receptor on target organ. It does not enter cell. The receptor activates 2nd messenger (cAMP usually)
Describe effects of Insulin on Blood Glucose.
- INSULIN DECREASES BLOOD GLUCOSE
- after meals when blood glucose increases, pancreas releases insulin, which triggers your liver to remove excess glucose from the blood & store it as glycogen
Describe the effects of Glucagon on Blood Glucose.
- GLUCAGON INCREASES BLOOD GLUCOSE
- Between meals Glucagon is released when blood glucose decreases too much, which causes liver to breakdown glycogen to glucose to enter blood
