What are peptide hormones degraded into? What occurs with these component parts? {Ans: Peptide hormones degraded into amino acids in the liver Amino acids can be used for 1.Gluconeogenesis 2.ATP generation 3.Creation of tissue proteins 4.Enter the nitrogen pool}Describe the activity of serotonin methyltransferase and whether it is light sensitive or insensitive {Ans: Adds a methyl group to serotonin Does not show regulation by pattern of light or dark exposure}Describe the steps of the phospholipase C pathway for lipid insoluble hormones {Ans: 1. Hormone binds to cell membrane receptor GPCR 2.Alpha unit of the G-Protein becomes phosphorylated and active 3. Alpha unit activates the cell membrane Phospholipase C 4.Phospholipase C creates PIP2 which creates diacylglycerol and IP3 5. Diacylglycerol directly increases the activity of protein kinase C 6. IP3 increases Ca release from the ER which indirectly increases Protein Kinase C activity 7. Increase in protein Kinase C activity leads to the physiological responses}Describe the function of adrenal androgens {Ans: Increases lipolysis Increase beta adrenergic receptors for epinephrine and norepinephrine Promotes neurogenesis and myogenesis Relaxes the myometrium prevents premature uterine contractions in pregnancy Increases the sex drive in women Slows the osteoporosis process}What are the amine
