  • Unit 1 Biology
    • Topic 1
      • CVD
        • Factors
        • Build up of atheroma causes plaque and blocks arteries, leads to CVD
      • Risk
        • Causation
          • A causes B
        • Correlation
          • A and B happen at the same time; a relationship.
      • Heart and circulation
        • Cardiac Cycle
          • Ventricular Systole
            • High pressure in ventricles AV valves close, blood goes into arteries, SL valves open.
          • Atria Systole
            • High pressure in attria, AV valves opne blood flows to ventricles.
          • Diastole
            • Both attria  and ventricles relax, blood comes into throughthe veins.
        • Single circulation
          • Oxygen and CO2 diffuse through cavities and blood is pumped to heart once.
      • Factors
      • Atherosclerosis
        • Endothelium of artery gets damaged
          • Cuases inflammatory  repsonse, WB cells, forms atheroma
            • Build up of atheroma causes plaque and blocks arteries, leads to CVD
    • Topic 2
      • Cistic Fibrosis
        • Genetic inheritance
      • DNA
        • Protein Synthesis
          • Translation
            • mRNA attaches to ribosome in cytoplasm, tRNA carry codoms and the corresponding amino acid and join to the mRNA. Polypetide chain is formed and dettaches.
          • Transcription
            • DNA unwinds, RNA is made using DNA templkate and base pairing, Thymine is replaced by Uracil
      • Cell membrane
        • Transport
          • Facilitated diffusion
            • Channel proteins
          • Osmosis
          • Diffusion
  • Replication
    • DNA
      • Protein Synthesis
        • Translation
          • mRNA attaches to ribosome in cytoplasm, tRNA carry codoms and the corresponding amino acid and join to the mRNA. Polypetide chain is formed and dettaches.
        • Transcription
          • DNA unwinds, RNA is made using DNA templkate and base pairing, Thymine is replaced by Uracil
    • Semi-conservative both old and new DNA strands together
  • Oxygen and CO2 diffuse through cavities and blood is pumped to heart once.
  • Structure
    • Double helix, 4 nitrogeneous bases; ATCG.
    • Phosphate group bonded to a pentose sugar phosphodiester bond and a nitrogen base
  • Double helix, 4 nitrogeneous bases; ATCG.
  • Structure
    • Cell membrane
      • Transport
        • Facilitated diffusion
          • Channel proteins
        • Osmosis
        • Diffusion
    • Phospholipid bilayer, hydrophillic head facing outwards, hydrophobic tail facing inwards.
  • Phospholipid bilayer, hydrophillic head facing outwards, hydrophobic tail facing inwards.
  • Carrier Proteins
