CHEM 1005 Biochemistry BioChem Midterm Question Bank latest 2020/2021 Questions: Hemoglobin has the ability to display cooperative binding while myoglobin does not display this binding kinetic patter... . Which of the following difference between the two proteins accounts for this difference in binding kinetics? An enzyme has a mutation within the substrate binding site that reduces the binding of the coenzyme needed for covalent catalysis. Which of the following is likely to result as a consequence of this mutation? A 19-year-old boy is diagnosed with Creutzfeldt-Jakob Disease which is caused by the introduction of an amyloid fold in the disease-causing protein. The introduction of this fold causes the protein to transition from a primarily α-helical structure to an aggregate of mostly β- sheets. This change in protein structure (leading to disease) is best attributed to changes in which of the following? Prosthetic groups are complex nonprotein molecules that participate in catalysis by providing functional groups that form a covalent intermediate between the enzyme and the substrate. Which of the following is an example of a coenzyme or cofactor that participates in a covalent catalysis reaction? [Show More]
