Ise the diagram below to answer Question B Lou L) 0% the HNo The figures show structures of amino acids, which are small biological molecules found in living cells. Each amino acid has a unique side chain, shown in the boxed portion of each figure. Which amino acid or acids have hydrophobic side chains? 8. a. b. c. d. Serine and asparagine Leucine only Leucine and phenylalanine Asparagine and leucine . 9 If a particular portion of a polypeptide is composed primarily of nonpolar amino acids and the protein is found in the blood, this region of the polypeptide will most likely be found... a. b. c. d. on the exterior of the protein, facing the blood on the interior of the protein, facing away from the blood on both the interior and exterior of the protein there is not enough information to determine the location 10. Which of the following amino acid changes is likely to cause the most structural change? a. acidic amino acidbasic amino acid b. acidic amino acid polar amino acid c, polar amino acid nonpolar amino acid d. polar amino acid ionic amino acid Substrate Enzyme Enzyme Image A e B 11. Using the images above, describe what is occurring to the structure and function, in both Image A and Image B. Describe specific conditions to which this occurs. 10Explanation / Answer
8) The correct answer is option C that is leucine and phenylalanine because they have water repelling tail that is hydrophobic tail.
Serine has an OH group, so it's a Hydrophillic amino acid.
Asparagine has an NH3 group that can also make Hydrogen bond, so it is also a Hydrophillic amino acid.
9) The correct answer is option B that is in the interior side of the protein facing away from the blood because hydrophobic amino acids are water repelling and blood is primarily composed of water. So, they will be in the interior of the blood so that they won't in contact with water.
10 - The correct answer is option C that is polar to non polar amino acid because in protein structure the most crucial thing is the hydrogen bond. When an amino acid is changed from polar to non polar then it won't be able to make Hydrogen bond.
11 - Enzyme is heated above 40°C and because of this it will lead enzyme to loose its structure because intra hydrogen bonds are broken due to high temperature.
In figure A it shown that as temperature rises, enzyme looses its three dimensional structure and substrate now won't be able to attach to the active site of the enzyme.
In B enzymes ribbon structure is shown to describe why substrate is not able to attach to the enzyme as its 3D structural has been lost.
