Hormone production
Example of hormone production sequence : insulin
| Hormone production sequence |
|---|
| A gene is a length of DNA |
| mRNA copy of the instructions (gene) for insulin is made in the nucleus |
| mRNA leaves the nuleus through the nuclear pore. |
| mRNA attaches to a ribosome in this case attached to endoplasmic reticulum. ribosomes read the instructions to assemble the protein. |
| Insulin molecules are 'pinched off' in a vesicle and travel towards the golgi apparatus. |
| the vesicle fuses with the golgi apparatus. |
| Golgi apparatus process and re-package insulin molecules ready for release |
| packaged insulin molecules are 'pinched off' in vesicles from the golgi apparatus and move towards the cell surface membrane. |
| the vesicle fuses with the cell surface membrane |
| The cell surface membrane opens to release insulin molecules outside |
