Study Notes

Golgi Apparatus

  • Dense aggregations of RNA and protein usually attached to the ER
  • Specialized portion of the endoplasmic reticulum, includes an array of parallel membranes and vesicles without ribosomes
  • Made up of various tubules and cisternae
  • Site of accumulation and concentration of secretory products of cell synthesis
  • Area where substances produced from the ER are modified, concentrated, and prepared for either transport or to be made into vesicles for secretion


  • "Powerhouse of the cell"
  • Slender rods or filaments enclosed by 2 membranes: outer membrane (smooth) and inner membrane (forms narrow folds to increase surface area)
  • Where oxidative metabolism occurs
  • Contains oxidative enzymes for breaking down glycogen and glucose into water and carbon dioxide
  • Liberated energy is used to synthesize triphosphate (ATP)


  • Contains hydrolytic enzymes that can break down proteins, deoxyribonucleic acids (DNA), and destroy/degade waste materials and foreign antigens
  • White blood cells, which phagocytose antigens, have lysosomes as essential parts of their intracellular digestive system
  • Can fuse with old organelles and cause them to be digested and recycled
  • Produced from the Golgi apparatus and secreted into vesicles
  • Responsible for recycling and defense of the cell

Learn about the Golgi apparatus, a specialized portion of the endoplasmic reticulum responsible for modifying, concentrating, and preparing cell products for transport or secretion. Explore its structure, function, and significance in cell biology.
