A&P - Chapter 5 (Part 2) Flashcards
What do ribosomes do?
Make proteins
What kind of membrane do ribosomes have?
No membrane
What 2 parts make up the ribosome?
- Large subunit rRNA
2. Small subunit rRNA
What happens when the ribosome is attached? (2)
- It makes proteins for use outside the cell
2. Embeds itself in the plasma membrane
What happens when the ribosome is free?
It makes proteins for use inside the cell
What is an enzyme an example of?
A protein
What RNA codes the protein?
rRNA
What is another word for protein?
Polypeptide
Does the golgi body have a membrane?
Yes
What does the golgi body look like?
Group of stacked, flattened sac
Where would you find the golgi body?
Near the nucleus
What does the golgi body do? (2)
- Receives proteins
2. Processes protein molecules from the ER
What happens after proteins are processed in the golgi body? (2)
- Packaged
2. Transported
Where does the golgi body transport the protein to get released?
The plasma membrane
What does the golgi body create?
Vesicles
- for tranport
What is created inside the cell that is meant to get out of the cell? (2)
- Enzymes
2. Hormones
Lysosomes
Microscopic membranous sacs that pinch off from the golgi body
What do lysosomes contain?
Digestive enzymes
What do digestive enzymes do?
They can destroy protein structures of damaged cell parts, microbes and other particles
What does ly mean?
Break
What does somes mean?
Body
What do lysosomes do? (2)
- They break down molecules
2. Clean the inside of the cell
What is the mitochondria the site for?
Cellular respiration
What is the mitochondria considered?
The power house of the cell
Where is energy released?
From the mitochondria
What does each mitochondria contain?
One DNA molecule
What does the DNA in the mitochondria allow it to do? (2)
- Produce its enzymes
2. Replicate itself
What are centrioles?
They are fine, rod shaped tubules that lie at right angles to each other near the nucleus
What are centrioles important for? (2)
- Cell reproduction
2. Cell division
