You were able to radioactively tag and thereby trace an amino acid that is used to make insulin, a hormone that will be exported out of the cell. The pathway of the tagged amino acid would be __________.
a) free ribosome → cytosol → vesicle → extracellular fluid
b) rough ER → Golgi complex → Golgi vesicle → extracellular fluid
c) rough ER → smooth ER → Golgi complex → Golgi vesicle → extracellular fluid
d) smooth ER → Golgi complex → Golgi vesicle → extracellular fluid
e) smooth ER → Golgi complex → lysosome → extracellular fluid

Respuesta :

Answer:

B) rough ER → Golgi complex → Golgi vesicle → extracellular fluid

Explanation:

  • Insulin is synhtesized by beta cells of pancereas (preproinsulin).
  • Insulin enters the rough endoplasmic reticulumn in its inactive form (proinsulin).
  • The rough endoplasmic reticulumn converts it to active form (insulin).
  • The rough endoplasmic reticulumn transfer the insulin to glogi comlpex
  • The Golgi complex secrete it in golgi vesicles to cytoplasm.
  • On the stimulation of beta cells insulin is secreted to extracellular fluid..

The labeled amino acid pathway would be Rough ER → Smooth ER Golgi Complex → Golgi Gallbladder → Extracellular Fluid

What is insulin and glucagon?

Insulin ensures the reduction of glucose levels, while glucagon ensures the increase of glucose in the body.

With this information, we can conclude that the labeled amino acid pathway would be Rough ER → Smooth ER Golgi Complex → Golgi Gallbladder → Extracellular Fluid
