Golgi Apparatus & Vesicles - Functions and Adaptations

Biology Review

Lumen

space inside golgi sacs where proteins and lipids are modified

Incoming transport vesicles

brings proteins and lipids from ER to golgi

Cis face

recieving side of the golgi that accepts vesicles from ER

Cisternae

flattened sacs that modify, sort, and package proteins and lipids

Secretory vesicle

transports finished products to cell surface

Trans face

shipping side of golgi where products are sorted and sent out

Newly forming vesicle

vesicle budding off the golgi to carry materials elsewhere

Flattened cisternae

large surface area for efficient protein and lipid modification

Stacked structure

allows step by step processing as materials move through golgi

enzyme-rich lumen

contains specific enzymes for chemical modification
