Question

A mutation from G rightarrow A causes a protein to lose its activity. Which level of protein structure is most likely affected and how? Explain your answer. You are simulating the first reaction of glycolysis in a test tube: Glucose + ATP rightarrow Glucose-6-PO_4 + ADP. You mix all the components (Glucose, ATP, ADP and Glucose-6-PO_4), making sure to match [Glc-6-PO_4][ADP]/[Glc][ATP] = K_eq for the reaction. You then add the hexokinase. What will happen? Will more Glucose + ATP be made? Will nothing happen? Explain your answer. A substrate binds tightly to the "X" domain of a protein. Would you expect the same substrate to bind to another protein that also has an "X" domain? Explain your answer. Which of the following statements are TRUE about isomers/isomerization? (Mark all that apply) They have different molecular masses Isomerization can result in different functional groups Isomers can have different physical properties Enzymes cannot differentiate between isomers Only carbohydrates can form isomers A molecule that has no chiral carbons cannot show isomerization

Explanation / Answer

17) of G to A mutation has occurred in first or second nucleotide of the there nucleotide codon then the amino acid will change in the sequence and it will lead to problem in protein's tertiary structure because that is responsible for the protein's activity. Like in cystic fibrosis a single codon change will have a lost function cl transporter. Tertiary structure is affected in the form of mutation in active site or the dilsulfide linkages in the tertiary structure.
