Day 6: You Won't Find This ER in a Hospital!

2:29 PM

Because these are the last two structures of our journey and they are rather close together in this cell, I decided to start late today. I needed a lie-in, anyway. *smirk*

Right now, we're at the rough endoplasmic reticulum (ER). This structure, which somewhat resembles the Golgi apparatus, its main function is packaging proteins. It works along the ribosomes to create the proteins; ribosomes creating amino acid chains. It's like the cell has its own FedEx!

The smooth ER acts as a storage place. It is important in the creation and storage of steroids especially. It also stores ions. Think of it as a garage, only instead of a plethora of objects inside, it's only a certain type.







5:30 PM
Our journey through the cell is complete. We have just exited the cell wall and are now in our natural habitat. Everything feels oddly huge, but I suppose it is to be expected after being inside of an object that is seen under a microscope for a week. I thank you for joining me on this adventure!

Yours,
--Mr. Kelley
