The Cell Flashcards
Do prokaryotes contain a nucleus or membrane-bound organelles?
No lol
What are fimbriae?
Hair-like structures on the outside of prokaryotes that help them stick
What are Pili?
Hair-like structures on the outside of bacteria used to attach and exchange DNA
What are Flagella?
Appendages used by bacteria to move
What is the nuclear envelope made from?
A double phospholipid bilayer
What protein helps compact DNA?
Histones
What are robosomes made form?
rRNA
Where are free ribosomes found and what is their function?
Free ribosomes are found in the cytoplasm
Their function is to make proteins that stay inside the cell
Where are bound ribosomes located and what is their function?
Bound ribosomes are bound to the Endoplasmic Reticulum
Their function is to make proteins that either go into the phospholipid bilayer cell membrane of proteins that get secreted from the cell
What are the 6 organelles involved in the endomembrane system?
- Nuclear Envelope
- Endoplasm Reticulum (smooth and rough)
- Golgi Apparatus
- Lysosomes
- Vacuoles
- Plasma membrane
How are members of the endomembrane system indirectly related?
With vesicles - membrane inclosed sacs which travel around the endomembrane system
What are some functions of the smooth E.R.
- drug and poison detoxification
- makes lipids
What is the main function of the rough E.R.?
Protein synthesis
How do newly synthesized proteins depart from the E.R. and where do they go?
Proteins depart from the E.R. in vesicles which are E.R. Membrane inclosed sacks which break off with the protein inside
Newly synthesized proteins get transported and fuse with the Golgi Apparatus
What is the Golgi Apparatus made up of?
Cisternae
