Questions about your lab??

I’m stamping it today. Late stamps will reflect in your Work Habits section of gradebook.

I’ll be grading it on Mon/Tuesday during your Unit Assessment

Does the cell membrane:1. Not let anything in2. Let anything in3. Let some particles in

We have a SEMI-PERMEABLE membrane…

There are three types of movement across the cell membrane:

1) Passive Transport2) Active Transport3) “Active” Transport

There are three types of movement across the cell membrane:

1. Passive Transport – movement of particles from high concentration to low concentration

• examples: diffusion (gas), osmosis (water)

2. Active Transport: Movement of particle from less concentrated to more concentrated

• Requires energy, ATP

2. Active Transport: Movement of particle from less concentrated to more concentrated

• Requires energy, ATPSodium Potassium Pump: pumps Na (sodium) and K (potassium) against their concentration gradients using ATP

• Against concentration gradient: low concentration moving to high concentration

Active Transport: Movement of particle from less concentrated to more concentrated

• Requires energy, ATPSodium Potassium Pump: pumps Na (sodium) and K (potassium) against their concentraion gradients using ATP

• Against concentration gradient: low concentration to high concentration

3. “Active” TransportEndocytosis: taking material into the cell by engulfing (surrounding) them in membrane

Endocytosis: taking material into the cell by engulfing (surrounding) them in membrane

Phagocytosis (cell eating): large solid particles are engulfed

Phagocytosis because…1. How amoebas capture

food particles2. Phagocytes are special

cells that defend against invading pathogens

3. Mammalian phagocytes dispose of more than 1011 aged blood cells per day

Endocytosis: taking material into the cell by engulfing (surrounding) them in membrane

Phagocytosis (cell eating): large solid particles are engulfedPinocytosis (cell drinking): liquid material is engulfed

Endocytosis: taking material into the cell by engulfing (surrounding) them in membrane

Phagocytosis (cell eating): large solid particles are engulfedPinocytosis (cell drinking): liquid material is engulfedReceptor mediated endocytosis: specific internalization of liquid material

Receptor mediated endocytosis:

A specific receptor on the membrane binds with a ligand

Examples of ligands:• Viruses• Proteins• Vitamins• Hormones• sugars

3. “Active” TransportEndocytosis: taking material into the cell by engulfing (surrounding) them in membraneExocytosis: releasing substances from a cell by the fusion of a vesicle with the membrane

Exocytosis because…1. Secrete proteins,

hormones, enzymes, antibodies

2. Make new plasma membrane

3. Place proteins in membrane

4. Immune response
