cell structure Flashcards
largest cell in your body?
neuron, 3 feet
the 3 components to the outside of a bacteria cell
capsule, cell wall, plasma membrane
what would you add to a bacterial cell to break its cell walls?
detergent
what powers the flagellum in a prokaryotic cell?
a rotary motor
what’s the difference in DNA storage in prokaryotes vs eukaryotes?
DNA in nucleus or out in cytoplasm
what components make up the nuclear envelope?
outer and inner nuclear membrane
nucleolus
nuclear subdomain that assembles ribosomal subunits in eukaryotic cells
chromatin
the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.
heterochromatin
dense, dark areas of chromatin- for INACTIVE genes- pushed to the edges
euchromatin
active genes, lighter color, on the inner parts of cell
where would you find the nuclear basket?
in the nuclear pore
which organelles are involved in the secretory pathway?
lysosome , ER, cell membrane, golgi apparatus
identify cis vs trans face of golgi appartus
cis: incoming receiving side from ER. trans: farthest away from ER.
phagocytosis
cell absorbing food particles, bacteria etc. it uses phagocytes
peroxisome
isolate hydrogen peroxide and use catalase enzyme to break it down
what is the matrix of a mitochrondria?
the inside of all of those folds
