Signal Transduction Pathways

Part A
Correct
This is a second messenger.
Part B
Correct
This is a signal molecule. The attachment of a signal molecule to a plasma membrane receptor initiates a signal transduction pathway.
Part C
Correct
This is the function of a transcription factor.
Part D
Correct
Activated transcription factors trigger transcription.
Part E
Correct
This is a receptor molecule.
Part F
Correct
The binding of a signal molecule to a receptor initiates a signal transduction pathway.
Part G
Correct
Cyclic AMP can act as second messengers.
Part H
Correct
The ER stores calcium ions.
Part I
Correct
Phospholipase C cleaves IP3 from a membrane protein, and IP3 then binds to a calcium channel on the ER.
Part J
Correct
By activating many other molecules the initial signal is amplified.
