SAMPLE QUESTIONS
Example Questions From the Test
- They enter through permanently open ion channels
- They are transported inward by ribosomes
- They dissolve only in the watery cytosol
- Their lipid-soluble nature lets them cross the plasma membrane
- Removal of phosphate groups from receptor serines
- Conversion of receptor proteins into membrane lipids
- Phosphorylation of tyrosines on the receptor tails
- Release of the receptors into the cytosol
- ATP is converted directly into receptor proteins
- More signaling ligands are synthesized outside the cell
- Membrane receptors become steroid hormones
- Phosphate groups are removed from pathway proteins more rapidly
WHAT THE TEST MEASURES
About This Assessment
Cell Communication Quiz - Symptoms and Signs
Test your understanding of how cells send, receive, amplify, and stop signals. This free 16-question cell communication quiz covers signaling types, membrane and intracellular receptors, second messengers, phosphorylation, GPCRs, receptor tyrosine kinases, gap junctions, and quorum sensing. Your final score places your knowledge in one of three clear ranges. No sign-up is needed to begin.
