4. Coupled Transport - One material (molecule) diffuses in passively and it, or the power of its diffusion will move another material against its concentration gradient.
Insulin/Glucose
B. Phagocytosis- engulfing particulate matter into the cell by engulfing it and then containing it into a vesicle.
C. Pinocytosis- same as phagocytosis but the material is liquid.
D. Receptor Mediated Endocytosis - molecule bonds to a receptor protein on the cell's surface and this activates a system that "pulls" the material in and contains it in a vesicle.
E. Exocytosis - the direct opposite of phagocytosis
VII. Protein Identification Markers - found on the external surface of a cell and ID's it as Foreign or Domestic and also as the type of tissue it is.
VIII. Endosymbiotic Theory- Eukaryotic Cells evolved from the phagocytosis and symbiotic cooperation of prokaryotic cells. Watch "Bozeman Biology-Endosymbiosis." Mitochondria and chloroplasts in particular show evidence that this has happened
A. Size and Shape are the same as aerobic bacilli Bacteria and Cyanobacteria (photosynthetic)
B. Mitochondria and Chloroplasts have a Double Membrane system:
1. Outer- came from the host cell. Same characteristics
2. Inner - folds and stacks just like Bacterial membranes. Used for the same purpose - make ATP
C. DNA
1. Have their own
2. DNA is circular
