Presentation Transcript

  1. Active Transport Molecule to be carried

  2. Active Transport • moves molecules from low concentration to high against a concentration gradient, requires ATP (energy), and may require transport proteins.

  3. Endocytosis & Exocytosis • Endocytosis • Movement of large materials INTO the cell. • Part of the cell membrane wraps around the particle and engulfs it. Exocytosis • Movement of large materials OUT OF the cell. • Vesicles from Golgi apparatus wrap around particle, combine with cell membrane, and then expel the particle from the cell.

  4. Endocytosis

  5. Endocytosis click • Phagocytosis: • “cell eating” • particles taken into cell • Pinocytosis: • “cell-drinking” • - fluid taken into cell

  6. Exocytosis
