The lecture Communication and Signaling – Protein Movement and Cell Signaling by Kevin Ahern, PhD is from the course Biochemistry: Basics.
Included Quiz Questions
Which of the following is true with respect to cellular signaling?
- It involves hormones.
- Signaling molecules enter cells through protein receptors.
- The term 7TM refers to a second messenger.
- The entire process occurs in the lipid bilayer.
- It generally goes from inside the cell to outside the cell.
Which of the following is a peptide hormone?
- Insulin
- Testosterone

- Epinephrine
Which of the following is a G-protein coupled receptor?

- Vitamin D receptor
- Testosterone receptor
- Estrogen receptor
- TSH receptor
What are 7-transmembrane receptors or G-protein coupled receptors?
- They are integral membrane proteins with seven membrane-spanning helices participating in signal transduction.
- They are non-membrane proteins that transduce the signal out of the cell.
- They are inside the cell membrane and do not have any specific function.
- They are highly hydrophilic membrane proteins that provide structural strength to the cell membrane.
- They are highly hydrophobic membrane proteins that provide shape to cell structures.
