Lysosomes

• What is the structure of a lysosome?

  Lysosomes are a type of Golgi vesicle with no obvious internal structure, membrane, digestive enzymes (lysozymes).
• What is the pH like?

  The pH inside the lysosome is acidic compared to the alkaline cytoplasm of the cell. This acidic pH is necessary for lysozymes to function.
• What is the function of lysosomes?

  Lysozymes inside lysosomes are responsible for digesting invading cells, old, unwanted parts of cells and complex biomolecules.
• What is the function of the membrane?

  The membrane ensures that the lysozymes are kept separate from the cytoplasm of the cell to prevent self-digestion.
