There are 20 amino acids needed to make proteins in the animal body. Why aren’t they all considered essential to animal diet?
Misty Copeland is taking a snack break from her 8-hour rehearsal day and she wants to aid her muscles with recovery by eating a protein-rich snack. Part 1: What is the name of the monomer used to synthesize the protein and what is the name of the covalent bond that holds these monomers together? Part 2: The cells lining the inside of Misty Copeland's stomach need to produce and secrete enzymes like pepsin that will help breakdown the protein-rich snack she just ate. Using your knowledge of the endomembrane system (1) describe the pathway taken by the newly synthesized enzymes that will be secreted by her stomach cells? Include the terms cis-facing and trans-facing in your answer. (2) Include the type of cellular transport required for the enzyme to leave the cell. Part 3: The pH of Misty's stomach is low. For enzymes not used to this environment, which levels of protein structure will be affected? Briefly explain why the level(s) of structure you selected are being impacted. Part 4: If…
