ID: 3482739 • Letter: M

Question

Match each hormone to the cell signalling pathway that matches it best.

A. binds to a receptor in the cell nucleus and directly stimulates synthesis of new proteins

B. activates IP3 second-messenger pathway, which floods the cell with Ca++

KEY WORDS: oxytocin, testosterone, glucagon

A researcher discovers a new water-soluble hormone. Which of the following statements would you expect to be true about it?

a.It directly affects gene transcription in the nucleus

b. It requires a carrier protein in the blood

c. It communicates using a second messenger system

Match each hormone to the cell signalling pathway that matches it best.

Question Selected Match

A. binds to a receptor in the cell nucleus and directly stimulates synthesis of new proteins

C. activates cAMP second-messenger pathway, which in turn activates and/or deactivates certain proteins within the cell.

B. activates IP3 second-messenger pathway, which floods the cell with Ca++

KEY WORDS: oxytocin, testosterone, glucagon

A researcher discovers a new water-soluble hormone. Which of the following statements would you expect to be true about it?

a.It directly affects gene transcription in the nucleus

b. It requires a carrier protein in the blood

c. It communicates using a second messenger system

Explanation / Answer

A.teststerone.steroid hormone bind to nuclear receptor.

B.oxytocin that activate ip3 second messanger syatem

C.glucagon peptide hormone. Activate cAMP pathway

Water soluble hormone it bind with DNA and directly affact gene transcription.

It travel freely in the blood.

It deirectly bind with DNA and affect gene transcription.

So statements. a nd b are correct.
