The correct answer is option I) Steroid hormones are lipid soluble and easily cross the phospholipid bilayer.

The steroid hormones are made up of steroid molecules, the steroid molecules are hydrophobic and lipid soluble.

How can competitive and noncompetitive inhibition be distinguished in terms of KM?
notsponge [240]

Answer:

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.
