Textbook Question
Chapter 5, Problem 8IQ
Now that you have gained experience with concept maps, create your own map to review what you have learned about proteins. Try to include the concepts of structure and function and look for cross-links on your map. Because proteins are complex, you may want to make several smaller maps to organize your knowledge. One version of a large protein concept map is included in the answer section, but remember that the real value is in the thinking process you must go through to create your own.

- Assume you want to make and study fragments of a protein. Would you expect that any fragment of the polypeptide chain would fold the same way as it would in the intact protein?arrow_forwardProtein A is a structural component while Protein B is an enzyme. Which could be characteristics of Protein A and Protein B? A. Protein A could have repetitive amino acid sequence while protein B be could have irregular amino acids. B. Protein B could be a type of collagen while Protein B could be a type of keratin. C. Protein A could be generally soluble in water while Protein B could be insoluble. D. Protein B could contain mainly αlpha-helix while Protein A could contain equal amounts of αlpha-helix and β-sheet. E. Protein A could be a globular protein while Protein B could be a fibrous protein.arrow_forwardProtein folding is critical for function because the properties of a protein arise from its overall shape and the distribution within that shape of the various amino acid side-chains. Which of the following statements about protein three-dimensional structure are correct? 1) the folding pattern of a protein is ultimately determined by its amino acid sequence. 2) proteins tend to fold in such a way that the hydrophobic amino acids are buried in the interior, while hydrophilic amino acids are exposed at the surface. 3) the chemical interactions within a protein molecule that support its overall folded structure are mostly covalent C-C (carbon to carbon) bonds between amino acid side-chains. 4) the overall folding pattern/shape of a protein molecule is termed its primary structure. 5) during evolution, the three-dimensional structure of a protein is often more strongly conserved than its amino acid sequence.
