Organelles- endomembrane system Flashcards
what process creates the right conditions for certain processes
compartmentalization of metabolic activities
what does the interior membrane system do
compartmentalization, control of internal surface areas
what is in the interior membrane (7)
nuclear envelope, endoplasmic reticulum (ER), Golgi, vesicles, lysosomes, vacuoles, plasma membrane
what does the nuclear envelope do
controls what goes in and out of the nucleus through pores
what is the rough ER for
protein synthesis, folding, and modification of proteins
why is it called the rough ER
it’s studded with ribosomes
what is the smooth ER for
lipid synthesis, detoxification
why is it called the smooth ER
has no ribosomes on it’s outside and tubular
what is the Golgi complex
the place where proteins are modified for their final function and sorted to be sent to other areas in vesicles
what are vesicles made of
the phospholipid bilayers
purpose of vesicles
to carry proteins and other things between compartments
what are lysosomes
the stomach of the cell
what are lysosome enzymes an example of
compartmentalization
what do lysosomes do
hydrolyses internal and external things
what are vacuoles
sacs filled with fluid
which cells are vacuoles found in
pant and fungi cells
purpose of vacuoles
pressure for cell enlargement, storing nutrients, digest of waste, pigmentation
purpose of plasma membrane
control what goes in and out of the cell
where can the plasma membrane be found
surrounding the cell
1st step in creating proteins
turning DNA into RNA which leaves the nucleus into the ER
2nd step of making proteins
proteins go through ER to mature by adding sugars, carbohydrates, etc.
3rd step of making proteins
proteins sent to golgi complex to be further matured and send elsewhere or stay in ER
