There is only 1 correct answer per question. 13. Humans require protein in a diet in combination with carbohydrate and fatty acids for the following reason: A. Protein is required as an energy source. ® Protein serves as a source of specific amino acids that cannot be synthesized de novo. C. Specific proteins are required in the diet because they cannot be synthesized by humans. D. Protein is required as a source of NADPH. E. Protein is required for the synthesis of ketone bodies. 14.

    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.
