Question 1 1 / 1 point Polymers are long chains of monomers (single units). Which of the following statements is/are correct with regard to this topic? The 4 macromolecules introduced in class (proteins, carbohydrates, nucleic acids, and lipids) are all polymers. The 20 monomers (amino acids) used to build proteins are alike in chemical properties. Polymers can be built by removing a water (an OH from the carboxyl end of one amino acid and an H from the amino group of the other) and building a covalent bond. Splitting a polymer into its monomers using a hydrolysis reaction always requires an input of energy. Question 2 1 / 1 point Proteins fold into the precise 3-dimensional shape needed to carry out their functions due to covalent bonds between parallel rows of beta-pleated sheets in the tertiary structure. weak interactions (such as H-bonding) between the side chains of the amino acid monomers. their primary structure (the exact sequence of amino acids).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
