Movement of substances across the plasma membrane

Movement of substances across the plasma membrane. Metabolism : all the chemical activities taking place in the cell Consists of two processes: Anabolism Catabolism. Anabolism : the building up of molecules E.g. : synthesis of protein and ATPs, which a cell needs Catabolism :

Cell Transport

Cell Transport. Cell Membrane. The membrane is mostly made up of phospholipids that have a hydrophilic heads and two hydrophobic tails. When these phospholipid molecules form the cell membrane, they arrange themselves in a bilayer that has a hydrophobic interior region
