Question

put the secretory protein synthesis actions in sequence from beginning to the end. vesicle fuses with plasma membrane to secrete proteins outside the cell peptides wrap in vesicle leaving ser, moving toward cis side of golgi apparatus ribosome and rna complex moves to rer membrane proteins leave golgi apparatus in vesicles rna leaves nucleus, enters cytosol gene transcribed into rna peptide is thread into rer membrane peptide is modified and sorted in golgi apparatus. then moves through golgi apparatus to exit from the trans - side of the organelle. ribosome latches on to rna to begin peptide synthesis peptide moves through rer, then ser

Explanation:

Protein synthesis starts with gene transcription into RNA in the nucleus. RNA then leaves the nucleus and enters the cytosol. A ribosome latches onto the RNA to begin peptide synthesis. The ribosome - RNA complex moves to the RER membrane and the peptide is threaded into the RER membrane. The peptide moves through the RER and then to the SER. Peptides wrap in a vesicle leaving the SER and move toward the cis - side of the Golgi apparatus. The peptide is modified and sorted in the Golgi apparatus and moves through it to exit from the trans - side. Proteins leave the Golgi apparatus in vesicles. Finally, the vesicle fuses with the plasma membrane to secrete proteins outside the cell.

Answer:

1. Gene transcribed into RNA
2. RNA leaves nucleus, enters cytosol
3. Ribosome latches on to RNA to begin peptide synthesis
4. Ribosome and RNA complex moves to RER membrane
5. Peptide is threaded into RER membrane
6. Peptide moves through RER, then SER
7. Peptides wrap in vesicle leaving SER, moving toward cis side of Golgi apparatus
8. Peptide is modified and sorted in Golgi apparatus. Then moves through Golgi apparatus to exit from the trans - side of the organelle
9. Proteins leave Golgi apparatus in vesicles
10. Vesicle fuses with plasma membrane to secrete proteins outside the cell
