Organelles Flashcards
. What is the nucleus?
The control center of the cell and the largest and most organized part of the Cell.
What kind of Er does the nucleus have?
Rough Er
What is the nucleus surrounded by?
Double membrane
What does the nuclear pores control?
What leaves and enters the nucleus
What is the chromatin?
A complex of DNA and proteins that make up chromosomes
Where are the ribosomal subunits formed?
The nucleolus
What are the ribosomal subunits?
rRNA and proteins
Where is ribosomes assembled?
The nucleolus
What is the function of ribosomes? (1)
Protein building
What are the distribution of ribosomes?
Free in cystosol and bound attached to rough Er
What is the difference between smooth Er and rough er?
Smooth has no ribosomes on surface while rough does
What are the functions of rough er? (Similar to Golgi apparatus) and sweat
Packages proteins for secretion, sends transport vesicles to Golgi and makes replacement membrane
What are the functions of smooth er?
Synthesizes lipids, metabolization of carbs, detox of drugs and poisons
What are the structures of the Golgi apparatus?
Cis face and trans face
What are the differences between the cis face and the trans face of the Golgi apparatus?
The cis face receives vesicles from the Er while in the trans face, the vesicles bud off
What are the functions of the Golgi apparatus? ( vesicles and proteins)
Modify, sort and concentrate proteins, pack proteins in vesicles and have vesicles deliver contents to outside of the cell.
What are vesicles containing digestive enzymes called?
Lysosomes
What is the ph of lysosomes?
4.5
What kinds of cells don’t usually have lysosomes?
Plant cells
What are the functions of lysosomes? (Destruction)
To destroy and recycle nonfunctional organelles, foreign particles and unneeded structures
What are the causes of the fatal lysosome diseases?
Digestive enzyme in lysosome not working correctly
