Mastering Biology: Chapter 5. Which of the following factors would tend to increase membrane fluidity?

By definition eukaryotic cells are cells that contain a membrane-bound nucleus, a structural feature that is not present in bacterial or archaeal cells. In addition to the nucleus eukaryotic cells are characterized by a number of organelles that are bound to a membrane such as the endoplasmic reticulum Golgi chloroplasts mitochondria and others. Continue reading Figure 2. An organelle is a structure within the cytoplasm of a eukaryotic cell that is surrounded by a membrane and performs a specific function.

Next Article. I woke up late today. I slept through three alarms, with only 20 minutes until my first class started. I jumped out of bed and walked across the hall to the bathroom. It was chilly in the morning, and I was not interested in switching my fleece-penguin pajama bottoms for a pair of blue jeans. Nobody would see them anyway. I headed back to my room and threw on a school hoodie. I hurriedly made my bed and opened the blinds in my room. The keyboard is plastered in Rutgers stickers, and the screen glowed pure blue. I traced my finger along the trackpad, and sure enough, the cursor had disappeared. I decided to restart it. The screen, after going black for a few minutes, started up again. I opened up my school and personal emails, catching myself up on any last-minute messages. With two minutes to spare, I raced down the stairs to grab a glass of water. Breakfast would have to wait.

This page has been archived and is no longer updated. The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell. Typically textbooks illustrate the Golgi as something resembling a stack of pita bread. However, this depiction does not adequately illustrate the dynamic nature of the Golgi compartments called cisternae or the variety of morphologies the Golgi manifests in different cell types. We can learn a lot by simply asking why these diverse structures even exist. Researchers do not yet fully understand how various Golgi morphologies affect its function.

We have already mentioned that vesicles can bud from the ER, but where do the vesicles go? Before reaching their final destination, the lipids or proteins within the transport vesicles need to be sorted, packaged, and tagged so that they wind up in the right place. The transport vesicles that form from the ER travel to the receiving face, fuse with it, and empty their contents into the lumen empty space inside of the Golgi apparatus. As the proteins and lipids travel through the Golgi, they undergo further modifications. The most frequent modification is the addition of short chains of sugar molecules. The newly modified proteins and lipids are then tagged with small molecular groups to enable them to be routed to their proper destinations. Finally, the modified and tagged proteins are packaged into vesicles that bud from the opposite face of the Golgi. While some of these vesicles, transport vesicles, deposit their contents into other parts of the cell where they will be used, others, secretory vesicles, fuse with the plasma membrane and release their contents outside the cell. The amount of Golgi in different cell types again illustrates that form follows function within cells.
