Question

Proteins destined for extracellular release are packaged in specific vesicles. After packaging, the vesicles bud off and are stored in the cell until a signal is given for their release. When the appropriate signal is received they move towards the membrane and fuse to release their contents.

Once proteins have been produced at the ribosomes, what two organelles work together to aid in the secretion process described above?
Responses
A ribosome and ERribosome and ER
B Golgi apparatus and rough ERGolgi apparatus and rough ER
C Golgi apparatus and lysosomeGolgi apparatus and lysosome
D mitochondria and rough endoplasmic reticulummitochondria and rough endoplasmic reticulum

B Golgi apparatus and rough ER

Question

Proteins are important biomolecules. Proteins are synthesized and often packaged for secretion into other cells within an organism. A variety of organelles play a role in producing, packaging, and moving proteins. Can you match the organelle with its function?
