Golgi complex—a small system of cisternae that synthesize carbohydrates and put the finishing touches on protein and glycoprotein synthesis
38Receives newly synthesized proteins from rough ER
Sorts them, cuts and splices some of them, adds carbohydrate moieties to some, and packages the protein into membrane-bound Golgi vesicles
Some become lysosomes
Some migrate to plasma membrane and fuse to it
Some become secretory vesicles for later release38
40Peroxisomes—resemble lysosomes but contain different enzymes and are not produced by the Golgi complex
General function is to use molecular oxygen to oxidize organic molecules
These reactions produce hydrogen peroxide (H2O2)
Catalase breaks down excess peroxide to H2O and O2
Neutralize free radicals, detoxify alcohol, other drugs, and a variety of blood-borne toxins
Break down fatty acids into acetyl groups for mitochondrial use in ATP synthesis
In all cells, but abundant in liver and kidney40
