1 Aim: How does the structure of the cell membrane contribute to its function? Como afecta la estructura de la membrana celular a su funcion?

2 Functions of the cell Membrane Funciones de la membrana celular  Protection  Controls what enters and exits  Has Receptors: Allows for cell communication Proteccion Controla lo que entra y sale Tiene receptores lo ayuda a la comunicacion celular

3 Receptors/ Receptores RECEPTORS Receptors (proteins in the membrane) allow for cell to cell communication. Son proteinas que permiten la comunicacion celular al recibir hormonas y neurotransmisores. By receiving hormones and neurotransmitters

4 Cell membrane Structure  Lipids/ Lipidos  Proteins/ Proteinas

5 Proteins and Lipids PROTEIN Lipid

6 Fluid: because the membrane moves Mosaic : because it is made of many pieces Se le llama un mosaico fluido: Mosaico- tiene muchas piezas Fluido- La memebrana se mueve

7 The cell membrane is SEMI- PERMEABLE-it allows materials through Permeable- La membrana celular es semi- permeable porque permite que pasen algunos materiales materiales pequenos como la glucosa. El almidon es muy grande y no pasa

8 Do all things get through the cell membrane? SELECTIVELY PERMEABLE
