Cell structure

• Lysosome

  Contains digestive enzymes
• Lysozymes

  Break down invading cells/foreign material or worn down parts of cells
• Centrioles

  Creates spindle fibres
• Ribosomes

  protein synthesis

  Translate mRNA to proteins
• Rough endometric reticulum

  Ribosomes attached

  Folding and processing proteins
• Smooth endoplasmic reticulum

  Lipid synthesis and processing
• Golgi apparatus

  • Takes proteins from RER and free ribosomes and lipids from SER
  • Processes and modifies them
  • Processed molecules bud off in vesicles
  • Either used in cell or leave by exocytosis
• Nucleus

  • Nuclear envelope- Double membrane with nuclear pores to allow movement of mRNA
  • Nucleoplasm- Made from chromotin
  • Nucleolus- Makes ribosomes
• Mitochondria

  • Produces ATP during respiration
  • Cristae- Respiration enzymes
  • Matrix- Contains circular DNA needed for mitochondria to function
