What part of the cell membrane is polar and allows the cell to exits in water?
The cell membrane is made out of two layers , a nonpolar and polar part. The polar part is the hydrophilic part , meaning water loving , and the nonpolar is hydrophobic part - water hating. The polar/hydrophilic part is inside of the membrane and the outer portion is the hydrophobic/nonpolar . You don't want the cell to exist in water or be soluble in water because then we would dissolve , all our cells , tissues etc. That's why the cell membranes outer portion is nonpolar and is not miscible with water . The cell membrane allows water molecules to come in and out of the cell by osmosis , and that is when water molecules can free out and in of the cell through the cell membrane .
What characteristics of a water molecule causes its attraction to a cell membrane?
The polarity of water molecules, due to their unequal distribution of charge, allows them to form hydrogen bonds with the polar head groups of phospholipids in the cell membrane. This attraction helps water molecules adhere to the membrane and interact with the hydrophilic regions of phospholipids. Additionally, the small size of water molecules enables them to move freely through the cell membrane.
What are the substances that the cell membrane does not allows to pass?
Usually Ions and charged molecules (salts dissolved in water), large polar molecules (glucose), and macromolecules.
What is the definition of polar head?
A polar head is the portion of a phospholipid molecule that is hydrophilic, meaning it is attracted to water. It is typically found on the outer surface of the cell membrane, facing the water-based environment inside and outside of the cell. The polar head allows phospholipids to form a stable bilayer structure in cell membranes.
