Biochemistry Western Governors University A: Fats are made up fatty acids and a glycerol. They are stored in cells known as adipocytes throughout the body. When the body needs energy the stored fats are broken down through the process of metabolism and beta oxidation (Livestrong.com‚ n.d.). For example‚ triacylglyceride or triglyceride are broken down into their separate parts‚ fatty acid chains and a glycerol. The body will always metabolize the glycerol first because it is easier

Cell Transport Mechanisms and Permeability 1 EXERCISE 1 OBJECTIVES 1. To define the following terms: differential permeability‚ passive and active processes of transport‚ diffusion (simple diffusion‚ facilitated dif- fusion‚ and osmosis)‚ solute pump‚ pinocytosis‚ and phagocytosis. 2. To describe the processes that account for the movement of sub- stances across the plasma membrane‚ and to indicate the driving force for each. 3. To determine which way substances will move passively

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The

was separated into four stages‚ the first being preparation of cell competency. In this stage two vials were placed in ice baths‚ one vial containing 50 µL of E. coli and the other containing a CaCl2 solution. 630 µL of the CaCl2 solution was then transferred to the E. coli vial‚ using a sterile pipet. After tapping the tube to mix the solution‚ it was then returned to the ice bath to continue incubation for at least 10 minutes. The cell competency preparation was carried out by the instructor in this

Biochemistry‚ GRT1 Task 2 Essential Amino Acid Valine A1: 2 Characteristics of Valine • Valine is a nonpolar amino acid‚ with many carbons surrounded by hydrogen. Valine is unable to interact with water molecules‚ making it HYDROPHOBIC (MSDS‚ 2005). • Flammability- Valine is combustible at high temperatures. These products are carbon oxides and nitrogen oxides. In case of a small fire‚ dry chemical powder should be utilized. In case of a large fire‚ utilize water spray‚ fog or foam. No water

Biochemistry GRT1 Lipids are molecules that are not soluble in water but can be dissolved in non-polar substances such as alcohol or chloroform (Mandal‚ n.d.). Lipid molecules are stored in adipose‚ or fat tissue‚ and can be broken down in our bodies to form an energy called ATP. To do so‚ the lipid molecule is dissected into its base pieces‚ glycerol and fatty acids. Each of the fatty acids is then broken down into two-carbon pieces and acetyl CoA is formed from each carbon
