1.2.1.1.10 Structures unique to animal cells:1.2.1.1.10.1 VesiclesA vesicle is a small, membrane-bound spherical sac which facilitates the metabolism, transport and storageof molecules. Many vesicles are made in the Golgi apparatus and the endoplasmic reticulum, or are madefrom parts of the cell membrane. Vesicles can be classied by their contents and function.• Transport vesicles transport molecules within the cell.• Lysosomes are formed by the Golgi apparatus and contain powerful enzymes that can potentiallydigest the cell. This compartmentalisation therefore protects the cell agains being digested by it'sown enzymes. Lysosomes play a role in protecting the cell by breaking down (digesting) harmful cellproducts, invading organisms, waste materials, and cellular debris in the cell. Lysosomes also breakdown cells that are ready to die, a process called autolysis.• Peroxisomes are vesicles that use oxygen to break down toxic substances in the cell and are common inthe liver and the kidney. Peroxisomes are named for the hydrogen peroxide (H2O2) that is producedwhen they break down organic compounds. Hydrogen peroxide is toxic, and in turn is broken downinto water (H2O) and oxygen (O2) molecules.33
