Lysosomes

Lysosomes and Peroxisomes
Lysosomes
Lysosomes are roughly spherical bodies bounded by a single membrane. They are manufactured by the Golgi apparatus (pathway 2 in the figure).

In the late endocytic pathway, it has been proposed that endocytosed macromolecules are delivered to a proteolytic environment by 'kiss-and-run' events or direct fusion between late endosomes and lysosomes.

Lysosomes are membrane-bound vesicles containing hydrolytic (digestive) enzymes produced by the Golgi complex.

Lysosomes (membrane-bound digestive vesicles) can digest macromolecules (break them down to small compounds) that were taken in from the outside of the cell by an endocytic vesicle.

lysosomes Membrane-enclosed organelles containing digestive enzymes. The lysosomes fuse with food vacuoles and enzymes contained within the lysosome chemically breakdown and/or digest the food vacuole's contents.

Lysosomes and Peroxisomes (the cellular digestive system) Lysosomes and peroxisomes are often referred to as the garbage disposal system of a cell.

As well as protein modification, Golgi apparatus is involved in the transport of lipids around the cell as well creating lysosomes -- organelles involved in digestion.

lysosome Cytoplasmic, membrane-bounded organelle that contains digestive and hydrolytic enzymes, which are typically most active at the acid pH found in the lumen of lysosomes.

organelle -- n. A membrane-bound structure in a eukaryotic cell that partitions the cell into regions which carry out different cellular functions, e.g., mitochondria, endoplasmic reticulum, lysosomes.
