Permeability of cell membrane

Question 1

permeability of cell membrane

Answer 1

• cell membrane surface is selectively permeable to water and some solutes
• non-polar substances can move through easier than polar substances
• lipid soluble can dissolve in phospholipids and diffuse across
• phospholipid layer hydrophobic, so lipid-soluble passes easier than water-soluble substances
• water soluble can’t diffuse through the phospholipids moves through intrinsic protein
