Shоrt Answer Set 2 SA 10. Define pаrаcrine, endоcrine, аnd synaptic signaling. SA 11. Identify оne mechanism that generates or maintains the asymmetric distribution of plasma membrane proteins in polarized cells. SA 12. Identify the three types of cell-surface receptors responsible for converting an extracellular signal into an intracellular response. SA 13. Identify two examples of activated carriers and the specific group carried in a high-energy linkage. SA 14. For cells grown under anaerobic conditions, explain the importance of converting pyruvate to ethanol (in yeast) or lactic acid (in muscle cells). SA 15. Transmembrane proteins can cross the lipid bilayer by adopting one of two types of secondary structures. Identify the name given to each of these folds. SA16. Identify 2 differences in the post-transcriptional processing of rRNA and tRNA. SA17. Describe what is meant by the ‘wobble position’ in codon-anticodon pairing and identify one benefit that arises from this event. SA18. The tryptophan repressor is an ‘allosterically regulated’ protein. Define ‘allostery’ in this context. Identify the small molecule that regulates the tryptophan repressor and indicate how the repressor functions in the presence/absence of this small molecule. SA19. Identify one mechanism that ensures a differentiated cell retains its identity following cell division.
