lipids based on hydrophobicity. • Unsaturated fatty acids have double bonds and increased membrane fluidity. • Cholesterol increases fluidity at low temperatures and decreases fluidity at high temperatures. • Ankyrin is a peripheral membrane protein found in erythrocytes. Therefore it lacks discrete hydrophobic sequences. • Most lipid-anchored proteins are attached to the inner side of a plasma membrane by covalent linkage to a fatty acid or prenyl group. • A useful technique for studying membrane

Review Sheet Exercise 1 Cell Transport Mechanisms and Permeability Activity 1: Simulating Dialysis (Simple Diffusion) • Describe two variables that affect the rate of diffusion: Two variables that affect the rate of diffusion are size and concentration gradient. The molecular size vs the MWCO size of the membrane can either increase‚ decrease‚ or prevent diffusion. The greater the concentration gradient the greater the diffusion rate due to molecules moving from areas of higher concentration

• What is the purpose of major crime-reporting programs? What makes a successful crime-reporting program in the United States? The purpose for major crime-reporting programs is to try to improve the methology and to publish the collective data. So by having major crime-reporting programs the law enforcement agencies are able to get information and also collect data to figure out the crime patterns of the nation instead of just one spot. This is hard though because not all of the crimes that end

Chemistry Essay: Electrochemical Cells By John Williams An electrochemical cell is s cell in which chemical energy in a redox reaction is converted to electrical energy. It consists of two half cells connected internally by a salt bridge and externally by wires. A hydrogen half cell is the standard electrode and all comparisons of the other half cells are made against this half cell which has an E( value of zero volts. The E( values of other half cells are obtained by measuring the total emf (electromotive

Sickle Cell Anemia is a hereditary disease that changes the smallest and most important components of the body. A gene causes the bone marrow in the body to make sickled shapes‚ when this happens; it causes the red blood cell to die faster. This is what causes Hemolytic Anemia. Older children and adults with sickle cell disease may experience a few complications‚ or have a pattern of ongoing problems that shorten their lives. The most common and serious complications of sickle cell disease are anemia

What are stem cells and what is gene therapy respectively? These are cells that have the potential to form many different types of cells found in the body. When stem cells divide‚ can form more stem cells or other cells that perform specialized functions. Embryonic stem cells have the potential to form a complete individual‚ while adult stem cells can only form certain types of specialized cells.
