Q//2
A//
1. The Regulation: Allosteric enzymes are regulated by molecules called
effectors (also called modifiers) that bind noncovalently at a site other than
the active site.
2. These enzymes are usually composed of multiple subunits, and the
regulatory (allosteric) site that binds the effector may be located on a subunit
that is not itself catalytic.
3. The presence of an allosteric effector can alter the affinity of the enzyme for
its substrate, or modify the maximal catalytic activity of the enzyme, or
both.
4. Effectors can be either positive (accelerate the enzyme-catalyzed reaction)
or negative (slow down the reaction) .
5. Allosteric enzymes frequently catalyze the committed step (slowest step) of a
pathway.
B// Electrophoresis (Def.) is a laboratory technique used to separate DNA, RNA or
protein molecules based on their size and electrical charge. An electric current is
used to move the molecules through a gel or other matrix.

Q//1
●Competitive inhibition
This type of inhibition occurs when the inhibitor binds reversibly to the
same site that the substrate would normally occupy and, therefore, competes
with the substrate for that site.
●Noncompetitive inhibition occurs when the inhibitor and substrate
bind at different sites on the enzyme.
