Proteins, which have diverse functions in a cell, are all polymers of the samekinds of monomers—amino acids. Write a short essay (100–150 words) that discusses how the structure of amino acids allows this one type of polymer to perform so many functions.
Draw the primary structure of a protein. Use the basic structure of an amino acid and label what type of bonds a protein has.
Kindly answer questions 8, 9 and 10. Put the letter of the answer.
1. Which of the following statements is accurate regarding these protein structures?
a. Proteins in a quaternary structure consist of a simple polypeptide chain.b. Interactions between the R groups in amino acids form tertiary structure.c. Secondary structures are formed by multiple polypeptide chains.d. The two types of primary structure are α- helices and β- pleated sheets.
2. What type of bonds are formed between amino acids?
a. Peptide bondb. Glycosidic linkagec. Hydrogen bondsd. Ester linkages
3. Which of the following is an example of protein denaturation?
a. Amino acids fold into repeating patterns due to hydrogen bonding of the peptide backbone.b. Several amino acids are joined together via peptide bonds.c. A protein binds with a substrate, lowering the activation energy of a reaction.d. A protein is exposed to extremely high heat, causing it to lose its secondary structure and be left with only its primary…
