lecture 6 (chemical signal transduction) Flashcards
1
Q
what do lipid-soluble chemical messengers do
A
binds to cytosolic or nuclear receptors, turns on genes to make new protein
2
Q
what do water-soluble (hydrophilic) chemical messengers do
A
binds to cell surface receptor, directly or through second messengers, alters activity of existing enzymes
3
Q
neurocrine signalling system
A
hydrophobic, can be stored in vesicles
4
Q
short-distance communication
A
docking, among stationary cells
5
Q
vibrio choleroe
A
-hormone-like chemical messengers lose control of system because choleroe toxins steal G-proteins
-let water and salt in
-die from water loss through diarrhea
