Question

suppose you were able to radioactively tag an amino acid that is used to make insulin, a hormone that will be exported out of the cell. put the following locations in order to trace the pathway of the tagged amino acid. rank the options below. golgi complex extracellular fluid transport vesicle rough er golgi vesicle

Explanation:

Insulin is a protein - hormone. Proteins are synthesized on ribosomes attached to the rough endoplasmic reticulum (Rough ER). Then they are transported to the Golgi complex in transport vesicles. At the Golgi complex, they are modified and packaged into Golgi vesicles. These vesicles then fuse with the cell membrane and release the insulin into the extracellular fluid.

Answer:

1. Rough ER
2. Golgi complex
3. Transport vesicle
4. Golgi vesicle
5. Extracellular fluid
