Cell physiology Flashcards
power house of the cell
mitochondria
cell physio: protein synthesis
RER, free floating ribosomes
cell physio: synthesis of lipids contains oxidases catalases for detoxification
SER
cell physio: contains lysozymes, lysoferritin and acid hydrolase
lysosome
cell physio: only substance modified in the RER not in the Golgi?
collagen
cell physio: motor protein causing transport from the cell body to the neural fibril
kinesin
cell physio: whip like movement on the cell surface found in the respiratory airways and fallopian tubes
ciliary movement
cell physio: what is the common component of the protoplasm?
water
cell physio: what is the common component of the cell membrane?
protein
cell physio: what is the most important component of the cell membrane?
cholesterol
the cell membrane is permeable to non-polar molecules true or false?
true
Junctional complexes: disk-shaped for firm intercellular adhesion eg epithelium
macula adherens (desmosomes)
Junctional complexes: for communication eg cardiac and smooth muscle
gap junctions
Junctional complexes: ring shaped increases surface area contact
zonula adherens
Junctional complexes: reticular either “tight” or “leaky”
zonula occludens (tight junctions)
functional unit of gap junctions?
connexons
movement of substance in both apical side and basolateral side?
transcellular transport
movement of substance through tight junctions
paracellular transport
T or F: the ff are correctly matched: clathrin:endocytosis & SNARE protein: exocytosis
true
lets discuss water transport. what’s the most common compound in your body?
water
whats the most common protein in your body?
collagen
what’s the most common amino acid?
glycine
which of the ff has a reflection coefficient closer to one? albumin or urea?
albumin
Transport: passive downhill non-carrier mediated
simple diffusion
