BioChem C785 module 2 quiz with complete solution

Which image below shows the carboxyl group of an amino acid circled? Answer-An amino acid consists of an amino group, carboxyl group, a hydrogen and a variable side chain arranged around a central alpha carbon atom. The backbone of an amino acid is the entire amino acid molecule minus the variable side chain. The carboxyl group of an amino acid is shown as COO_ or COOH attached to a central alpha carbon atom of the amino acid. Which of the following statements is NOT true about the different levels of a protein structure? AnswerThe interactions between the side chains of the amino acids make up the secondary level structure of a protein Which statement reflects the role that protein structure can play in the disease process? AnswerMutation of an active site amino acid changes an enzyme's ability to bind a substrate.
