Cells Flashcards
Are they active or passive transport ??
> Simple diffusion
channel mediated facilitated diffusion
Carrier mediated facilitated diffusion
Passive
What kind of materials go through channel mediated facilitated diffusion ?
Water soluble materials example … sodium, postassium, calcium
Why is ATP needed?
To help substances move from lower concentration to higher !!
What is the cytosol of the cytoplasm
Intracellualar fluid & surrounds organelles
What percentage of water forms the cytosol?
75-90%
Cytoskeleton function?
Cellular movement
Keeps the general shape & structure
Centrosomes function?
Used for formation of mitotic spindle
Cilium function?
Moves extracellur fluids
Flagella?
Moves the cell
Ribosome
Protein synthesis
Rough ER
Rough: synthesizes glycoproteins
ER: > Synthesizes fatty acids & steroids
> releases Ca+ into muscles 💪
> inactivates drugs
Golgi complex ?
> Lipid and protein synthesis
accepts proteins
transport
Lysosome ?
Digests dead foreign bodies
Peroxisome?
> > Oxidizes fatty acids & amino acids
Deactivates alcohol
Mitachondrion
> ATP synthesis
aerobic respiration
Vesicle?
Releases materials from extra cellular fluids into extracellur (outside) (exocytosis)
What Type of muscle cell would have multiple cell nuclei?
Skeletal
What is the nucleus surrounded by?
Nuclear envelope
What are the layers called of the nuclear envelope?
They’re similar to the plasma membranes one?
Phospholipid bilayer ?
Or
Lipid bilayer?
Lipid bilayer
what is the litter layer of the nuclear envelope attached to🧐? What organelle?
Rough ER
Revision: ions pass through with diffusion and larger things like RNA & proteins pass by an ACTIVE process !!!
What do nucleoli produce?
Hint: the main function is protein synthesis?
Ribosomes
What does the DNA in a nucleus direct?
The metabolic activities
RNA is involved in what synthesis ?
Hint: Ribosomes
Protein synthesis
