Active Transport

• Requires energy to move materials UP their concentration gradient, from an area of lower concentration to an area of higher concentration.

• The opposite direction for diffusion.

Mar 26­7:42 p.m.

Transport Proteins• Substances are moved molecule by 

     molecule.

• It is similar to facilitated diffusion except that cell energy (ATP) is used in the 

     process.

ATP = Adenosine Triphosphate

Two Types of Endocytosis• Pinocytosis = Cell drinking ­ transport of solvents or fluids

• Phagocytosis = Cell eating ­ movement of large particles or whole cells.  (Many unicellular organisms feed by phagocytosis)

• Phagocytes = cells like white blood cells, which use phagocytosis to ingest bacteria and viruses that invade the body.  Lysosomal enzymes then digest the invaders before they cause harm.

Mar 26­7:42 p.m.

Exocytosis

• The reverse of endocytosis

• Vesicles in the cell fuse with the membrane and release contents to the outside.

(a) Describe ONE similarity (other than size) in the structure of these two cells for absorbing materials.

(b) Explain how this similarity affects how these cells absorb materials.

(c) Osmosis and active transport are both processes used by cells. Compare and contrast these two processes.
