Protein synthesis organelles working together

Question 1

Explain how different organelles in protein production work together

Answer 1

1)mRNA copy of a gene is made in nucleus
2)mRNA leaves through nuclear pore and attaches to a ribosome and assembles protein ( at rough ER)
3)protein pinched off as vesicle and goes
to Golgi where it fuses and is packaged.
4) packaged protein pinched off Golgi in vesicles and move to plasma membrane
5)There protein fuses to membrane which opens and releases protein (exocytoss)

Question 2

what are the 3 destinations
the proteins in vesicles leave to?

Answer 2

• become enzymes in lysosomes
• inserted into cell surface membrane
• secreted from cell (exocytosis )
e.g. antibodies
