Allosteric Modulation

Q.

Allosteric modulation is due to the inhibitory action of enzyme by

1. Non-competitive inhibition

2. Enzyme concentration

3. Substrate concentration

4. Products of reaction

5. Competitive inhibition

Q.

Substances, which obstruct enzyme activity are called ___.

Q. Feedback inhibition of enzyme is due to

1. substrate accumulation
2. structural similarity between substrate and inhibitor
3. accumulation of end product
4. accumulation of inhibitor

Q.

Which one of the following characteristics best applies to an allosteric effector?

1. Competes with the substrate for the catalytic site

2. Binds to a site on the enzyme molecule distinct from the catalytic site

3. Changes the nature of the product formed

4. Changes substrate specificity of the enzyme
