  • Bacteria And Viruses Essay

    Nucleic Acid Contains genetic material, which may be double or single stranded DNA or RNA. This allows for the synthesis of viral proteins. Tail Fibres Allow the virus to attach to host cell and move. Lipid Envelope (Dervied from host cell membrane) Fuses with the host's membrane, allowing the capside and viral genome to enter and infect the host. Capsomere Repeating protein unit, which makes up the protein coat. In order for a virus to infect a cell…

  • Summary: The Nisin Bacteriocin

    The Nisin Bacteriocin Introduction Nisin is a bacteriosin peptide made up of 34 amino acid residues that contain uncommon amino acids such as lanthionine and didehydroalanine. It is a substance produced by both gram positive and gram negative bacteria to control the growth of other bacteria species to reduce competition for substrate and space. Nisin has received attention from researchers making it the most exploited bacteriosin (Shetty, Pometto and Levin, 2006). The attention from…

  • Rhodopsin In ROS Membranes Case Study

    of rhodopsin in ROS membranes resulted in viewing this visual receptor as monomeric entity freely diffusing in a phospholipid bilayer (Calvert et al., 2001; Chabre et al., 2003; Liebman et al., 1982; Poo and Cone, 1974). However, it is important to stress that the movement of rhodopsin restricted to approximately two-dimensional environment of membranous phospholipid bilayer would rather reduce its dynamic freedom by orders of magnitude relative to soluble proteins. Such reduction in diffusion…

  • Influenza Virus: Pandemics

    thereby releasing newly assembled virions from the cell surface and preventing the self-aggregation of virus particles (Watanbe et al, 2010). ).M2 is a very minor component of the envelope, with only 16 to20 molecules per virion. Underneath the lipid bilayer lies the matrix protein (M1), a major structural protein. Within the virus shell are eight viral ribonucleoprotein (vRNP) complexes, each composed of viral RNA associated with the nucleoprotein NP and the three components of the viral RNA…

  • Fatty Acid Synthesis: The Catalysis Process Of Biosynthesis

    It is also called anabolism or biogenesis. It is a enzyme-catalyzed method in which substrates are transformed into complex products. In this process simple compounds change or convert into other compounds or they join together to form macromolecules. Example: In this process gluneogenesis is responsible for the production of glucose from non carbohydrate originator. Actually biosynthesis is an enzyme-catalyzed process in which substrates are converted into complex compounds. 1. Biosynthesis…

  • Cancer Argument Essay

    Cancer is a disease that have been infecting people for centuries. It is also the leading cause of disease worldwide. According to the cancer research group in the uk, in the year 2012 there was an estimate of 14.1 million new cases of cancer. This was split 53% in males and 47% in females. Several cancer types exists and I will be focusing on breast cancer. In the years 2013 the American Cancer Society stated that there was 64,640 new in Situ cases and 232,340 new invasive cases. In situ cancer…

  • Triclosan Research Paper

    Bacterial cells have a cell membrane made up of a bilayer of lipids that is embedded with proteins that allow wastes to exit the cell and nutrients to enter. Lipids are long chains of hydrocarbons that are essential to cell membrane growth and function. Certain enzymes speed up the process of hydrocarbon elongation. Triclosan stops the building of lipid chains by binding to the active site of the enzyme and stopping the process of elongation of the lipid chain and thus stopping the growth of…

  • Animal Cell Structure

    this is not their only position, they can also be found freely within the cell cytoplasm (the area within the cell that contains the cell organelles) The S.E.R is in charge of storing, and secreting non-protein products such as carbohydrates and lipids etc. (kent, 2000,…

  • Roles Of The Endocrine System

    cell, so those hormones need to cross the cell membrane to be able to connect with their receptors. The cell membrane contains the lipid bilayer which those hormone has to pass, the only hormones that can do that are the fat-soluble hormones, which are form from the cholesterol. The cell membrane hormone receptors as the name suggested can be found outside…

  • Similarities Between Prokaryotic And Eukaryotic Cells

    HIV subsists as a virion outside its host. Therefore, its’ surface is covered in proteins, specifically gp120, which interacts with CD4, a protein on the surface of particular white blood cells, which eventually lead to entry to the host. HIV has a lipid-containing outer envelope derived from host cell membranes upon infection of host. The structures within a cell are measured in two different units: micrometer (μm) and nanometer (nm). A micrometer is equal to 10-6 meters and one nanometer is…
