PPT-Active Transport,

Endocytosis and Exocytosis Section 35 1 Objectives SWBAT describe active transport SWBAT distinguish among endocytosis exocytosis and phagocytosis Main Ideas Proteins can transport materials against a concentration gradient. Diffusion. : The passive movement of particles from a region of high concentration to a region of low concentration until equilibrium is reached. (Molecules still move after equilibrium is reached) . Essential idea: Membranes control the composition of cells by active and passive transport.. The . background image is . a piece of artwork inspired by the complexity of an . E. Coli. .

Introduction. All microbes have a need for three things: carbon, energy, and . electrons.. Nutrients are substances in the environment used by organisms for catabolism and anabolism.. Active Transport Driven by ATP Hydrolysis. The net flow of molecules by facilitated diffusion, through either carrier proteins or channel proteins, is always energetically downhill in the direction determined by electrochemical gradients across the membrane. .
