cell parts Flashcards
1
Q
function of SER
A
make lipids
metabolise carbs
store proteins for cells that don’t make then
2
Q
what does SER store
A
enzymes - liver
ca2+ - muscle
3
Q
what does RER make
A
secreted, membrane, organelle proteins
4
Q
microtubule function
A
cell shape and size
chomosome organisation
move organelles/cilia/flagella
5
Q
intermediate filament function
A
tension, scaffold, bear weight
6
Q
microfilament function
A
amoeboid militily muscle contraction bear tenson and weight by attaching cytoskeleton to PM anchor cytoskeleton support microvilli
7
Q
microfilament structure and location
A
around the periphery of cell
in microvilli
2 strands of actin intertwined
8
Q
DNA folding hierarchy
A
DNA –> nucleosomes –> chromatin –> looped domains –> chromatids –> chromosomes
9
Q
what are the functions of membrane proteins
A
cell joining cell communication (allows passage of substances and signal transduction) enzyme activity cell recognition attach to ECM Transport of substances
