protoglandins |
mod fatty acids or gases |
|
NO3 |
regulates and NO transmitters activate enzyme for vasodilation (inc blood flow to tissues) |
|
classes of hormones |
pp's, steroids, amines 'insulin': has 2 chains in active form |
|
Cell response pathways |
water vs. lipid soluble signalling mlecules |
|
Pathway for Water Soluble hormones Water Soluble |
exocytosis (in blood) non-diffusable: thru plasma membrane in target cells. diffuse: into cytoplasm target cells. Hormone and receptor make cell response, activates enzymes, changes molecules by moving cytoplasm to nucleus. |
|
Pathway for Water Soluble hormones
signal transduction |
EC signal becomes IC response. In hormone signalling, kidneys make adrenaline when stressed |
|
Pathway for Lipid Soluble Hormones |
IC receptors transduce signal in the cell -> activates recptor -> changes expression |
|
Pathway for Lipid Soluble Hormones hormones + receptor |
complex + nucleus undergoes tanscriprion ( + DNA binding protein or DNA response element) makes mRNA for proteins SA yolk or hormones + target cell = egg white |
|
Pathway for Lipid Soluble Hormones non-steroids |
(lipid soluble) have receptors in the nucelus +
hormone = transcription |
