2. Aim: How can we compare active and passive transport?/ Como podemos comparar transportes activo y pasivo?

3. Do all things get through the cell membrane? SELECTIVELY PERMEABLE Water Molecules

4. Types of cell transport/ Tipos de transporte Celular Active transport Transporte Activo Energy required Necesita energia Against concentration gradient Va en contra de la corriente de concentracion From low to high Va de bajo a alto Passive transport Transporte pasivo No energy required No requiere energia Down the concentration gradient Baja con el gradiente de concentracion From high to low De alto a bajo

5. Passive Transport/Transporte Pasivo Diffusion = movement of O2 & CO2 Facilitated diffusion = alcohols & glucose (needs membrane protein) Osmosis = movement of H2O Difusión = movimiento de O2 y CO2 Difusion facilitada = alcoholes y glucosa (necesita la proteína de la membrana) Osmosis = movimiento de H2O

6. Active Transport/Transporte Activo PhagocytosisPinocytosis
