Cell Membrane Labelling Phospholipid Cholesterol Peripheral Protein Carbohydrate Carrier Protein Integral Protein Matching Simple Diffusion Does not require energy. High to Low concentration Facilitated Diffusion Does not require energy. Uses a protein channel. Active Transport Low to high concentration. Makes use of ATP Endocytosis Moves molecules inward by use of a vessicle Exocytosis moves molecules outward by use of a vessicle Draw an example of a isotonic, hypotonic (turgid), and hypertonic (flaccid) cell.
