Which of the Following is Not True About Integral Proteins

Question

Which of the following is not true about integral proteins?
A) They interact with the nonpolar lipid tails embedded in the membrane.
B) They disassemble into individual molecules of tubulin.
C) They have hydrophobic and hydrophilic regions.
D) They are transmembrane proteins that protrude on both sides.
E) They have some of the same actions as peripheral proteins.

Accepted Answer

Integral proteins do not disassemble into tubulin, which is a protein that makes up microtubules, not a component or characteristic of integral membrane proteins. Integral proteins are known for their interaction with the membrane's hydrophobic core, having both hydrophobic and hydrophilic regions, being transmembrane proteins, and sharing some functions with peripheral proteins.
