So exited my shipments are almost done! I have been working SOOO hard to get all my packages ready to be used and address, but now they are DONE! All I have to do now is ship them to the Lysosomes, the plasma membrane of the cell, AND outside the cell! REJOICE this is truly a good day:)
Cisternae is the name of my sisters, but we are so close they are practically a part of me. (They actually are a part of me.) I usually have four to eight sisters depending on my unicellular house, but when I am in single-celled houses I could have sixty sisters. They are made of matrix proteins, but we are all made of cytoplasmic microtubules. In each house I notice three types of personalities (3 types of cisternae). The sisters who are nearest to the Endoplasmic Reticulum, I call them “cis“, the sisters who are near my center, “medial“, and finally, and the sisters who are far away from the ER, “trans“.

AYYYE ITs ME! GOLGI!
This week ER and I had a BLAST, as usual. We have work together and it is so fun seeing her. She is one of the hardest working organelles I know and since you already know about my job, here is some info about how we work together. Protein synthesis begins when mRNA (messenger RNA) transfers from the nucleus to a ribosome and the ribosome transfers an amino acid chain to the Rough ER. When the proteins are produced, finalized, and completed quality control in the lumen of the ER, they pinch off the organelle surrounded in a vesicle. Traveling through the vesicular-tubular cluster, a intermediate trafficking compartment between the Golgi Body and the ER, they finally reach me and I complete my many processing tasks we previously learned about.
Because this week is so pretty, I encourage you to all play with you bestie/BFF/bestfriend!!! Have I ever told you about my best friend? Her name is endoplasmic reticulum and she looks like a bunch of flattish sacs that are very compex because she is a string of membranous tubules. It is really fun because we are neighbors, so whenever I need some proteins or lipids, the components she makes, she will bring them right over! She consists of fifty percent of an animal cell’s membrane surface and you can find her in a eukaryotic cell working on her extracurriculars, protein/lipid synthesis, as well as compleating the process of translation, assembling proteins. Although she is SUPER great and REALLY hard working, she has her fair share of flaws! Number One. She is closer and more connected to the envelope of the nucleus than to me! Here I am thinking she and I are so close, but they are CONNECTED! UGH… and also she is soo moody. That brings us to Number two. She is totally two faced! I mean literally, she tells me that both faces are just a co-existing part of who she is, like sub compartments of herself that are made up of the same membranes just different functions, but idk anymore. Here is an example. When cells are in need of larger amounts of protein you can find more of her rough personality (Rough ER), but then if a cell needs more lipids and steroid hormones, then you can find more of a soft personality (Smooth ER). So her smooth personality is the “storage” personality and is always producing lipids and steroids. (Fun Fact: The ER is smooth because there are no Ribosomes and it can be covered in “slippery fats.” It can also detoxify chemicals and adapt them to be water-soluble and less toxic.) Oh! and this personality also has a another variation called the sarcoplasmic reticulum that is similar, but works to store ions. OK, so her other face is the Rough face. ( Rough ER/ RER) Annoying wannabe ribosomes always follow this part of her around, attaching to her membrane, and synthesis as well as package proteins, constantly compleating protein synthesis.

Today was really mediocre….
My job is so time consuming. How am I supposed to catch up on my latest show if I am always getting the macromolecules ready and shipping them?? AND DON’T even get me started on modifying proteins and lipids!! My job is so tedious because it’s practically an assembly line creating post translational modifications. At each stop, Just so you know, I create different reactions, so that later when the lipids and proteins bud off, they go to the right place. In simple terms I take fairly simple molecules and make them complex, pack them in vesicles, and then ship them to their destination. (LIKE UPS & FEDEX) Thanks to me, lysosomes are also built. This is my job, but humans are always disagreeing weather I am moving or the macromolecules are moving through me. Silly humans, if only I could tell, but my lips are sealed.
GALS it’s mE!
SOOO I never really told you about who I am, which is probably pretty important. Anyways, I process, package, and ship things in need of transportation in a cell. I take the macromolecules and WHOOSH they are ready for use/exocytosis. You could call me FexEx or even UPS and my mail could be packages of proteins and lipids. (My function is similar to an assembly line.) Also if you were wondering what I look like.. I look like a bunch of flat tubes and sacs, even though that does not sound appealing, I promise that I always catch the nucleolus staring & i am proud to be a golgi!!

Hey its me, GOLGI!
It has been 118 years since 1898, the day I made my debut into the world. You see, I was always around, but in this year Camillo Golgi discovered me!! It was quite an honor you see because he was a very smart man (and a noble prize winner), but my discovery turned out to be an accident. I made history and was overwhelmed with my newfound fame, after he wrote a book about me, “apparato reticolare interno.” (He was Italian)
