Golgi aparathus is an organelle that is found in eukaryotic cells. Soluble protein can enter Golgi aparathus in folded conformation because the golgi aparathus is a complex vessicles and folded membrane that help to package, transport and modify proteins and deliver them to the right location they will be needed.
This is parasitism because one organism (mosquito) is benefitting (by acquiring nutrition) and the other organism (human) is harmed (by the red itchy bump).
