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
... [Show More] 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.
Aggregation of the proteins is the main reason behind many neurodegenerative diseases. Which one of
the following mutations will likely cause a neurodegenerative disease? Answer-Replacing a polar amino
acid with a non polar amino acid
Which pair (protein interaction and technique) will likely denature a protein? Answer-Hydrogen
bonds/ionic bonds: Change in pH
Which one of the following statements is NOT true about protein structure and stability? AnswerProtein structure is not stabilized by the hydrophobic effect
Alkaline phosphatase is produced by bone and liver in the human body. The amount of alkaline
phosphatase in blood can help identify if a patient potentially has certain types of bone and/or liverrelated disease, including Paget disease, hepatitis, and certain types of cancer. The optimal pH range for
alkaline phosphatase activity is a pH of 8.0 to 10.0. What happens to the activity of the alkaline
phosphatase at a pH of 2? Answer-Significantly decreases
Inhibitors that have a similar structure to a substrate of an enzyme are most likely to bind to the
enzyme's ____________ and be a ____________ inhibitor. Answer-active site, competitive [Show Less]
