Summarize the sequence of processing, sorting, and transport of proteins synthesized in a human cell. Then indicate which cell component corresponds with each number above
ANSWER: Proteins made on ribosomes attached to the endoplasmic reticulum (ER) are transferred to the
interior of the ER, where they are folded and chemically modified. Many of these proteins
are transported to the Golgi complex in vesicles. In the Golgi, the proteins are further
modified, sorted, and packaged into vesicles for delivery to other parts of the cell and are
incorporated into organelles such as lysosomes or are transported to the surface for insertion
into the plasma membrane. Proteins also can be packaged into vesicles for secretion.
The diagram is labeled as follows:1
) nucleus
2) ribosome
3) vesicle
4) protein
5) cytoplasm
6) Golgi complex
7) lysosome
8) plasma membrane
