1 Experiment Membrane Transport Objectives ► Referring to energy‚ what two ways can substances enter a cell? What is active transport? What is passive transport? How is osmosis related to diffusion? How can we demonstrate active transport? How can we demonstrate Brownian movement? How can we demonstrate diffusion (2 ways)? How can we demonstrate osmosis (3 ways)? In terms of relationships between substances‚ how can we define “hypertonic”‚ “isotonic”‚ and “hypotonic”? What is the relationship

Transport Across The Plasma Membrane Intracellular Fluid (ICF) – The two thirds of your body fluid contained inside body cells. (Intra = within). The cytosol of the cell. Extracellular Fluid (ECF) – Fluid outside the body cells. (extra = outside). Interstitial Fluid – The ECF in tiny spaces between cells (inter = between). Plasma- the ECF in blood vessels. Lymph- The ECF in lymphatic vessels. Solute – Any material dissolved in fluid. Solvent- The fluid a Solute is dissolved in. Concentration

Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The

London congestion charge zone (urban toll) = the last solution for traffic-jams ? Which alternative ? Since the 17 February 2003‚ a congestion charge zone was established in Central London‚ and extended into parts of west London on 19 February 2007. Each vehicle has to pay £8 for a day for travelling within the zone between 7am and 6pm (Monday-Friday). It aims to reduce congestion‚ pollution and raise investment funds for London’s transport system. There are no tollbooths or barrier to enter the
