Question
The following is true for competitive inhibition. a. Inhibitor binds at the active site b. Inhibitor binds at the allosteric site c. Inhibitor competes with substrate for binding d. A and b are true e. A and c are true Kinases require binding to Magnesium (Mg++) ion. This is an example of a. Cofactor b. Coenzyme c. Inhibitor d. Effector The following is true for Allosteic enzymes. a. Their activity involves structural changes b. They do not exhibit Michelis-Menten behavior c. They exhibit cooperativity d. All of the above are true The shape of activity of Allosteric enzyme is a. Linear b. Hyperbola c. Logarithmic d. Sigmoidal Coenzymes are a. Small ions b. Organic compounds The following is true for induced-fit model. a. It describes substrate induced change in enzyme shape. b. It describes that binding between substrate and active site is specific. c. When enzyme binds to the substrates, an ES complex is formed before products are made d. All of the above are trueExplanation / Answer
Q1. Option (e) is correct nswer. Inhibitor binds at the active site and competes with the substrate.
Q2. Option (a) is correct answer. Cofactors are usually metal ions. Coenzymes are non-protien organic compounds.
Q3. Option (d) is the correct answer. Allosteiric enzymes possess all these charaters.
Q4. Option (d) is the correct answer. The cooperativity results in SIGMOID shape of activity of the allosteirc enzymes.
Q5. Coenzymes are organic compounds. Hence option (b) is correct answer.
Q6. Option (d) is the correct answer.
