  • Biology - Section 1 Cells
    • Eukaryotic Cells
      • Golgi Apparatus
        • Fluid-filled flattened sacs
        • Processes and packages new lipids and proteins
        • Makes lysosomes
      • Membrane bound DNA
        • Nucleus and nucleolus
        • Nulcear membrane
        • Nuclear pores
        • Chromatim
      • Mitochondria
        • Double membrane
        • Folded membrace is cristae
        • Inside is the matrix
        • Site of respiration, where ATP is released
      • Large ribosomes
        • Where proteins are translated
      • Endoplasmic Recticulum
        • System of membranes enclosing a fluid-filled space
        • Smooth ER synthesises and processes lipids
        • Rough ER folds and processes proteins
      • Lysosomes
        • Contain digestive enzymes
        • Break down dead or invading cells
      • Linear DNA
      • Centioles
        • Involved in the separation of chromosomes during cell division
      • Vesicles
        • Transport substabnces
    • Prokaryotic Cells
      • Circular DNA
      • DNA is free in cytoplams
      • Small ribosomes
        • Where proteins are translated
      • Cell wall
        • Polysaccharide
    • Protein Transport
      • 1. Proteins are made at the ribosomes
      • 2. These proteins are folded and processed at the rER
      • 3. hey're then transported to the golgi in vesicles
      • 4. /here they undergo further processing
      • 5. The protenis enter more vesicles to be transported around the cell
