How can competitive and noncompetitive inhibition be distinguished in terms of km?
a. the apparent value of km decreases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor.
b. the apparent value of km increases with a competitive inhibitor, while it decreases with a noncompetitive inhibitor.
c. the apparent value of km increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor.
d. the apparent value of km remains unchanged with a competitive inhibitor, while it increases for a noncompetitive inhibitor.

The correct answer is option c. "The apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor".

Explanation:

The KM value in an enzymatic reaction is defined as the substrate concentration at which the half of the enzyme molecules are binding with the substrate. A way to distinguish between a competitive and noncompetitive inhibition is that the apparent value of KM increases with a competitive inhibitor, while it remains unchanged with a noncompetitive inhibitor. A competitive inhibitor would make that a higher concentration of substrate is needed, while a noncompetitive inhibitor does not change KM since the inhibitor binds to a site of the enzyme different from the active site.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
