Lysosomes in Biological Definition

Golgi apparatus

... function is to process proteins targeted to the plasma membrane, lysosomes or endosomes and those that will be secreted from the cell, and sort them ... is involved in the transport of lipids around the cell as well creating lysosomes -- organelles involved in digestion . ...

Vesicle

... reticulum , or are made from parts of the plasma membrane . lysosomes (membrane-bound digestive vesicles) can digest macromolecules (break them ... to protect the cell interior from being digested by its own enzyme. lysosomes are made in the Golgi apparatus. Neurons store neurotransmitters in ...

Cytoplasm

... and the cell's interior is liquid. The insoluble constituents of the cytoplasm are organelles (such as the mitochondria , the chloroplast , lysosomes , peroxysomes , ribosomes ), several vacuoles , cytoskeletons as well as complex membrane structures (e.g. endoplasmic reticulums or the ...

Endomembrane system

... endoplasmic reticulum is an extension of the nuclear envelope]. The Golgi apparatus acts as the packaging and delivery system for molecules. lysosomes are the "digestive" units of the cell. They utilize enzymes to break down macromolecules and also act as a waste disposal system. Vacuoles act ...

Eukaryote

... modified in stacks of flattened vesicles, called Golgi bodies or dictyosomes. Vesicles may be specialized for various purposes. For instance, lysosomes contain enzymes that break down the contents of food vacuoles, and peroxisomes are used to break down peroxide which is toxic otherwise. Many ...

Major histocompatibility complex

... cytosolic as in class I). Loading of class II molecules must still occur inside the cell; extracellular proteins are endocytosed , digested in lysosomes , and bound by the class II MHC molecule prior to the molecule's migration to the plasma membrane. The peptides are longer, generally between 15-24 ...

Peroxisome

... that separates them from the cytosol (the internal fluid of the cell). Peroxisomes were discovered by Christian de Duve in 1965 . Unlike lysosomes , which are formed in the Golgi apparatus , peroxisomes usually self-replicate by enlarging and then dividing, although there is some indication new ...
