The most abundant organelle in liver cells is the smooth endoplasmic reticulum. The nucleus is an organelle found in eukaryotic cells. Myosin V is involved in vesicle and organelle transport. Many chemicals damage mitochondria, an intracellular organelle that produces energy. An mtDNA is genetic material contained in the cellular organelle called the mitochondria. A lysosome () is a membrane-bound organelle found in many animal cells. A rhoptry is a specialized secretory organelle. Catalase is usually located in a cellular organelle called the peroxisome. It kills malaria by targeting a plastid organelle, the apicoplast. A hydrogenosome is a membrane bound, redox active organelle. The extracellular domain just externally from the cell or organelle. The nucleus is the largest organelle in animal cells. Trophozoites adhere to host epithelial cells via a specialized disk-shaped organelle called the ventral disk. A major advantage of liposomes is their ability to fuse to cell and organelle membranes. Unclassified microorganism should be further checked for organelle sequences.
