Presentation Transcript

  1. Cell Membranes and Transport Getting material in and out of cells

  2. Transport • Getting material in and out of cells • Can be broken into two categories

  3. Passive Transport • Movement of material in/out of cells • CELL USES NO ENERGY TO DO SO • Diffusion: (From Hi  Lo) • Down the concentration gradient.

  4. Active Transport • Cell USES ENERGY to move material in/out cells. • “Up” the concentration gradient: (Lo  Hi) • Uses the protein channels in the cell membrane.

  5. Active Transport • Receptor Mediated Endocytosis – Bringing large molecules or chunky bits into the cell. • Cell surrounds and “engulfs” the material • Phagocytosis – Cellular “eating” • Pinocytosis – Cell “drinking” • The reverse process is called Exocytosis – Cell “Pooping” Animation
