Homework Answers
Answer- a small uncharged molecule
A cell is having a lipid bilayer as a boundary. The cell membrane separates cellular content from surrounding.
The cell membrane is composed of lipids, proteins, and carbohydrates. Phospholipids are amphipathic molecules, have a hydrophilic head and hydrophobic fatty acid chains.
The small uncharged molecule can pass through lipid bilayer as they are soluble in the lipid bilayer. The large polar molecule cannot cross the lipid bilayer.
Please give a thumbs up!!!!!!!! Ask any doubts regarding the above question in the comment section !!!!!!!!!!! Thank you!!!!!
