Golgi Body Flashcards
What is the Golgi body?
A cell organelle that packages lipids and proteins to be transported out of the cell.
Is the Golgi body found in eukaryotic or prokaryotic cells?
The Golgi body is only found within eukaryotic cells.
What is another name for the Golgi body?
The Golgi apparatus.
What is the name of the system that the Golgi body is apart of?
The Endomembrane System.
What is the endomembrane system?
A system of cellular structures, including the endoplasmic reticulum, nuclear envelope, Golgi body, and vesicles, that is used to synthesize and package proteins and lipids.
What does the Golgi body look like?
A bunch of flattened sacs (or “pancake stacks”) between the endoplasmic reticulum and the plasma membrane.
What do enzymes do in the Golgi body?
They help to finish the production of proteins and lipids that began in the endoplasmic reticulum.
What are the steps of the endomembrane system? (Simplified)
- Proteins and Lipids start at the Endoplasmic Reticulum
- They are then handed off to the Golgi body
- The Proteins and Lipids are finished off and packaged in the Golgi body
- Once they are finished off, they are packaged into something called a vesicle.
What is a vesicle?
A tiny sac surrounded by a membrane that contains the finished product and will transport the finished product from the Golgi body, through the cytoplasm, to wherever it needs to go in the cell.
How do vesicles know where to go?
Enzymes or tag molecules will be added to the vesicle, they tell it where to go within the cell.
Can vesicles contain enzymes?
Yes. Alongside the different molecules they can carry, vesicles can also carry enzymes that help to break down substances within the cell.
What is a lysosome?
A type of vesicle that transports enzymes. These enzymes help to break down materials within the cell, such as bacteria or cell parts. Anything that a cell does not want inside it can be broken down by lysosomes.
