Feedback inhibition is defined as a mechanism of down-regulating enzyme activity by the accumulation of a product earlier in the pathway. True or False, please explain
Homework Answers
The answer is TRUE
Explanation: To ensure that the product concentration is regulated, in an enzyme catalysed reaction the product itself acts as the inhibitor of the enzyme activity thereby inhibiting its own production. The higher concentration of the product results in binding of the product to the allosteric site of the enzyme resulting in inhibition of the enzyme activity.
Eg. In human body cholesterol is produced in liver as it is an important structural component of the cells. But high amount of cholesterol in blood results in inhibition of cholesterol production in the liver.
Another example is production of ATP from glucose. If ATP is not being used up, ATP binds allosterically to the first enzyme of glucose breakdown resulting in inhibiting its activity.

Microbiology In the competitive inhibition of enzyme activity, which statement is correct? Inhibitor directly competes with the substrate. Less substrates must be added in order to reach Vmax. The number of active sites is unlimited. None of the above. In the noncompetitive inhibition of enzyme activity, which statement is correct?Inhibitors will cause a conformational change in the enzyme, more substrate must be added to reach Vmax, Enzymes bound to the inhibitor can still bind substrate, none of the above. ....
