A day in the life

My day today started like any other, still connected to the nucleus. I know it's convenient, since all the information I need to do my job is in the nucleus, but sometimes I long to travel to the distant cell membrane at the farthest reaches of the cell.

Anyway, the cell had a lot of protein to make today, so bits of mRNA were floating out of the nucleus bright and early. My ribosomes (I love those guys, all embedded on my membrane) did a great job turning those orders from the nucleus into perfect proteins, with the help of some enzymes.

As soon as the ribosomes finished a protein, I dutifully passed it along to the Golgi apparatus in a custom-made vesicle I made out of my own membrane.

It's tough work, but someone has to do it, or the cell would die.
