- HOW MANY DIFFERENT PROTEINS CAN BE CONSTRUCTED THAT ARE EXACTLY FOUR AMINO ACIDS LONG? (HINT: THERE ARE 20 POSSIBLE AMINO ACIDS.)arrow_forwardWhat results in the alteration of amino acid sequences during polypeptide formation in protein synthesis? A defective polypeptide may arise because of a change in its amino acid sequence Despite the change in amino acid sequence, the polypeptide formed will always be functional and will never cause a disease. The cell will have no other choice but to revert the faulty polypeptide into amino acids to undo its work. The nucleus, by means of its powerful enzymes, will eventually destroy the damaged protein so that it will not wreak havoc in the cell.arrow_forwardWhy are multifunctional proteins necessary and/ordesirable?arrow_forward

- What are the amino acid requirements of proteins and how are they are placed within the membrane?arrow_forwardThe proteins in an organism’s cells are diverse (in number) and complex (in structure and function). How is this so when there are only 20 amino acids that would make them?arrow_forwardIn the figure below, protein 1 is located in the cytosol, and protein 2 is membrane bound. Give 3 specific examples from Figure 4-3 of amino acids that you might expect to find on the surface of protein 1. For protein 2, give three specific amino acids that you would expect to be on the surface near both points A and B (labeled with stars). To clarify, you should choose 3 amino acids for point A and also list three amino acids for point B. All of the amino acids you choose for Protein 2 must be different from those that you choose for Protein 1. Rationalize your choices by discussing the amino acids you chose, and their properties in a few sentences. Protein 1 Protein 2arrow_forward
