cell organelles Flashcards
what is the role of the nucleus?
- has info and blueprints
- gene controlled : tells other parts of cell what to do
ER stands for what?
endoplasmic reticulum
Rough ER has what?
little ribosomes
what is a Ribosomes’ function?
Produce protein site of protein synthesis
Smooth ER is responsible for?
- making lipids
- breaking down the toxins
Golgi complex: newly made proteins are transported here and can go where?
- to different parts of the cell
- outside the cell
lysosomes break…
down material when its not used
vacuole is important in ..
storage
what are the 2 energy organelles?
mitochondria and chloroplast
mitochondria is used for ?
making ATP
chloroplasts make ?
sugar
what are ribosomes made of?
- proteins
- RNA (ribosomal RNA)
where are ribosome synthesized?
nucleolus in nucleus
how many subunits make up a ribosome?
2!!! a small and a large
why does mRNA go through the middle?
translating the message of the messenger RNA to a protein
what is the ER usually attached to?
outside the nucleus
rough ER have ribosomes on it so..
it can synthesize proteins
smooth ER are where lipids are..?
synthesized
the function of the ER is to be a lattice so cells can?
build things
what are some accomplishments about Camilo Golgi?
- stained cells
- figuring parts of cells using stains
what are the 3 purposes of lysosomes?
- digest material
- fuse with viruses
- dissolve mitochondria that’s not functioning
why are lysosomes referred to as the suicide sack?
has enzymes that break down material when its not needed anymore
what is the mitochondria’s’ purpose?
cellular respiration and energy producer
mitochondria*
why is there folding on the cristae and why is this significant?
to increase surface area and make more ATP
