Sketch a section of a phospholipid bilayer of a membrane, and label the hydrophilic head and hydrophobic tail of one of the phospholipids.

The hydrophobic tails are sandwiched in between because they are ‘water-hating’ leaving the hydrophilic ends (which are ‘water-loving’) to interact with the watery environment inside and outside of the cell. The hydrophobic ends are mainly made of fatty acid chains ( and have no charges) while the hydrophilic ends are made of phosphate molecules that are negatively charged.

. ph changes the ability of them he enzyme to dissolve in water.
