4.4: Changes in Signal Transduction Pathways Flashcards
1
Q
What would happen if there was a mutation in the receptor protein?
A
It would not be able to bind to the ligand, so there would be no signal transduction.
2
Q
What would happen if there was a mutation in a transduction protein?
A
The signal would not be received.
3
Q
How can a chemical interfere with the signaling pathway?
A
They can bind to receptors, or prevent the signaling molecules from leaving.
4
Q
Identify one example of a chemical that activates a signaling pathway.
A
Fibroblast
5
Q
Identify one example of a chemical that inhibits a signaling pathway.
A
GABA
