Question

31) Which of the following levels of protein structure may be disrupted by boiling at 100° c A) Primary B) Secondary C) Tertiary D) A and B E) B and C 32) Which of the following statements is/are true concerning allosteric inhibition? A) Binding of the inhibitor to the allosteric site reduces the activity of the enzyme. B) Binding of the substrate to the active (substrate) site prevents binding of the inhibitor to the al C) It is part of feedback inhibition. D) All of the above E) A and C 33) Which of the following is/are shared by negative and positive control of transcription? A) Activator binding site B) Operator C) Promoter D) A and C E) B and C

Explanation / Answer

31-E

32-D

33-E

Note - the allosteric inhibitor bind to allosteric site while substrate bind to active site both of binding bring about conformational changes in enzyme which doesnot allow binding further to either one .
