Which of the statement about cell membrane is not true?

Correct answer: C. It contains charged pores thus ions being charged particles across cell membrane much easier than neutral particles

  • A. It contains protein molecules embedded in lipid bilayer
  • B. It is a differentially permeable membrane
  • C. It contains charged pores thus ions being charged particles across cell membrane much easier than neutral particles
  • D. it may get infolded to engulf solid or liquid material

Explanation

The substances which are lipid soluble cross it more easily than others, therefore, it regulates the low of materials and ions to maintain a definite gradient. Many small gas molecules, water, glucose, etc. being neutral can easily cross while ions, being charged particles, have some difficulty in crossing. Many substances which are not needed, constantly enter the cell by passive transport
