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

that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to enter the inside of the cell. Osmosis is the process of water movement across the membranes from an area of high water concentration to an area of low water concentration to reach a sense of equilibrium. Diffusion is what enables osmosis to occur.

Roots of the Cold War I. Growing Distrust 1. FDR‚ Churchill and Stalin met at a Soviet Union resort called Yalta. Stalin promised that he would hold free elections in parts of Eastern Europe under his control. 2. Instead‚ Stalin set of Communist governments in the nations. He wanted a ring of friendly countries to protect the Soviet Union’s southern border. With this‚ Stalin hoped that the Soviet Union would become the world’s dominant power. 3. By 1948‚ most of the countries in Eastern

are in an area‚ the more collisions there will be. These collisions cause molecules to push away from each other. So‚ over time‚ the molecules of a substance will continue to spread out. Eventually‚ they will be spread evenly throughout the area. Osmosis is the diffusion of water. (when “the substance” that is diffusing is water)

How to Freeze Taro Root Overview A large tuberous vegetable‚ taro has white flesh and an earthy taste somewhat like potato and somewhat like chestnut. Toxic when raw‚ taro requires cooking before eating. Taro flesh turns gray‚ purplish-red or yellow during cooking. You may use taro in just about any recipe that calls for potatoes. Always serve taro hot because it undergoes an unpleasant texture change as it gets cold. Step 1 Wash and peel the taro. Wear gloves or oil your hands well for this

Diffusion and Osmosis Lab Introduction • What molecules can pass through a semi-permeable membrane? In this lab study we tested carbohydrates such as starch and glucose‚ as well as solutions like Benedict’s and Lugol’s to see if they would cross the membrane of a cell but since we can’t actually see that happen we used dialysis tubing (acts as the cell membrane). • My prediction was that glucose and Benedict’s could pass the semi-permeable membrane but starch and Lugol’s wouldn’t be able to
