Cellular Compartments And Organelles Flashcards
What is the function of a lipid?
The function of a lipid is to block anything non polar or hydrophilic from entering the cell.
How would you explain the structure of a plasma membrane?
All plasma membranes are surrounded by water. Plasma membranes include hydrophilic heads that are polar (water loving) and hydrophobic heads that are non polar (non water loving). With all of these components in tact, the plasma membrane forms a bilayer.
What is transport protein consist of?
Selecting certain things to get through the cell through channel proteins. The protein must change shape in order to match the transport protein.
What is the main function of the cytoplasm?
It consists of “soup” proteins, enzymes, dissolved salts and sugars. All of the organelles and the nucleus float in the cytoplasm.
What do ribosomes consist of?
RNA and proteins
Where are the two places in the cell where ribosomes can be found?
Free floating in the cytoplasm or bound to the ER to give it the rough surface.
What is the main function of a ribosome?
To synthesize proteins
What is the main function of the Rough ER?
It’s responsible for transporting proteins into and out of the cell. It can also be used as a storage area.
What is the main difference between the Rough ER and the smooth ER?
The smooth ER contains no ribosomes.
What is the main function of the smooth ER?
It’s used as the site for lipid (membrane) synthesis.
What part of the cell does the Golgi Body connect to?
Smooth ER
What is the main function of the Golgi Body?
It completes lipid synthesis and sorts proteins to their correct destination in small vesicles.
What two functions are the vesicles responsible for in the cell?
They are responsible for transporting proteins and lipids to the cells surface. They also digest proteins in lysosomes.
What is the main function of a lysosome?
It is responsible for digesting and/or destroying enzymes and it also recycles damaged organelles.
What is the main function of a peroxisome?
It is responsible for breaking down fatty acids, amino acids, and alcohol.
