Question

Question 3 1.88 / 5 pts Consider the following amino acids: Glutamine, Valine, Arginine, and Glutamate. For each scenario, state which amino acid is most likely to be found and why (no more than 1 sentence each): a. Contained within the phospholipid bilayer of a cell. b. Involved in the deprotonation of Histidine. c. In the exposed region of an extracellular receptor. d. Electrostatically interacting with the phosphate backbone of DNA. Your Answer: A) Valine because it is nonpolar so it is hydrophobic b) Arginine because it is acidic and it will accept a proton from histidine c) glutamate because it is acidic and is often used as a recptor d) Glutamine because it is polar and does Hydrogen bonding 3b, 3c, and 3d is amino acid incorrect 3c and 3d reasoning incorrect

a. Contained within the phospholipid bilayer of a cell.
b. Involved in the deprotonation of Histidine.
c. In the exposed region of an extracellular receptor.
d. Electrostatically interacting with the phosphate backbone of DNA.
Your Answer:
A) Valine because it is nonpolar so it is hydrophobic
b) Arginine because it is acidic and it will accept a proton from histidine
c) glutamate because it is acidic and is often used as a recptor
d) Glutamine because it is polar and does Hydrogen bonding
3b, 3c, and 3d is amino acid incorrect 3c and 3d reasoning
incorrect
