Functional Anatomy of Prokaryotic and Eukaryotic Cells PowerPoint Lecture Slide Presentation prepared by Christine L. Case Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Plasma Membrane Selective permeability allows passage of some molecules Enzymes for ATP production

Photosynthetic pigments on foldings called chromatophores or thylakoids Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Plasma Membrane Damage to the membrane by alcohols, quaternary ammonium (detergents) and polymyxin antibiotics causes leakage of cell contents.

Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Movement Across Membranes Simple diffusion: Movement of a solute from an area of high concentration to an area of low concentration. Facilitative diffusion: Solute combines with a transporter protein in the membrane. Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings

Movement Across Membranes Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Figure 4.17 Movement Across Membranes Osmosis Movement of water across a selectively permeable membrane

from an area of high water concentration to an area of lower water. Osmotic pressure The pressure needed to stop the movement of water across the membrane. Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Figure 4.18a

Copyright 2004 Pearson Education, Inc., publishing as Benjamin Cummings Figure 4.18c-e Movement Across Membranes Active transport of substances requires a transporter protein and ATP. Group translocation of substances requires a transporter protein and PEP.
