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

warming and cause many climate problems (National Atmospheric Emissions Inventory‚ 2008). One of the major greenhouse gases is carbon dioxide (CO2)‚ and the major emissions of CO2 are come from the combustion of fossil fuels in power generation‚ transport and industrial sectors (Figure 1). In order to have a better understanding of this issue‚ the first step is to analyze how many CO2 we have emitted in our daily life.

Cellular Transport Worksheet KEY OSMOSIS Copy the pictures below‚ and write the correct type of solution underneath (isotonic‚ hypertonic‚ or hypotonic) Hypotonic Hypertonic Isotonic Hypertonic means there is a GREATER concentration of solute molecules OUTSIDE the cell than inside. Hypo tonic means there is a LOWER concentration of solute molecules OUTSIDE the cell than inside. Isotonic means there

Kinder transport The killing of children was supported was by the Nazis during the Holocaust. Children were helpless and could not always fight for their survival. With this 1.5 million children were killed by the Germans. Countries wanted to help these children‚ Jewish and non- Jewish‚ for their fate. These children’s fate was categorized in many ways. Some of these ways were; as they arrived in killing centers‚ after birth‚ those who survived because prisoners hid them‚ kids over twelve who

I would like to start with types of transport to introduce this question‚ because transport is important part to accomplish our holidays‚ hobbies or daily life even. We can divide transport means into two parts. The first is public transport and the second is private. The most common and the cheapest public transport in our republic is bus‚ then follow the train‚ the tube‚ taxi and the most expensive is traveling by airplane. These different types of transport also depend on the distance we are going

of public transport This is a website informing towards young people some advantages and disadvantages of public transport. Many of us are in these days use our own vehicles to get to our destination and utilizing it as our ‘daily use’‚ whereas numbers of public transport are reducing since many people are passing their driving test and buying their own cars. This is leading to pollution in the Earth; hence I will be mentioning some advantages and disadvantages of public transport. Firstly

CELL TRANSPORT MECHANISMS AND PERMEABILITY Zack Johnson Human Anatomy & Physiology Lab 2101 Instructor: Alan Byboth‚ M.S. 10/4/12 Abstract- The cell is invaluable building block of all biological life on this planet‚ and one of its most important and unique characteristics is its ability to be selectively permeable with its plasma membrane. This outer membrane’s sophisticated mechanisms of transport through its bilayer are vital in maintaining homeostasis in the cell and the entire

Lab 1: Cell Transport Mechanisms and Permeability Purpose The purpose of this experiment is to have a better understanding of the subject matter and to understand the difference between active and passive cellular transport. It will also help to define diffusion and describe the process that occurs when certain solutes come in contact and are either stopped or move through the plasma membrane. Hypothesis I believe the plasma membrane is selective about what is able to and not able to pass
