BIO/BCHM Flashcards
these cells known to be very proliferate - divide
epithelial cells
these do not typically undergo cell division post mitotic
neurons
early in life these cells of proliferative but as we age, the mitotic capacity these cells dec
cardiac muscle cells
these cells are unlikely to go division, respond to changing conditions by altering their size
adipocutes
this amino acid only one has sulfhydrl groups
cysteine
if theres a dec in ATp synthesis/levels but there is still same concentration of ATP in both cells why??
glycolytic flux is increased after treatment - allows to provide for that extra ATP (ETC activity was low - so CAC is not helping)
in the ETC researchers ned to determine the activity of the complexes independant? why
rx catalyzed by complexes are coupled to one another
a large carb tagged with flu marker and placed extracellular around a macrophage - ingest carb via phagocytosis - which cell structure will be labelled upon viewing a light microscope upon phago
lysoszyme
during phago large molecules enter into the ____ and this ca fuse with____ which have ____
phagosome, lysoszyjme, and hydroltic enzymes
what inhibits PFK
ATP, citrate, and acidic ph
inhibition of PFK example of what inhibitions
feedback, competitive
inhibiting K channel in AP diagram will cause
delay repolarization, prolong AP
At a ph below protein pI it will be
positive charge
ph above pI it will be
negative
if a protein suggests it activate expression, trancribe has TF then must have this sequence
nuclear locatlization
in the transmembrane domian what kind of molecules are in th emiddle
nonpolar
is the flu is low when in solution with acid (aqueos)
then surface a.a. of the protein are mostly hydrophilic in aqueous solution
what will happen if the inner membrane of mitochondrial is permeable
dirupt the gradient - proton gradient will disspate
histone acetylation is a ____ and so it will be detected on
post translational modification — wester blot,
Vasopressin regulated the insertion of aquaporins into the apical membrane of epithelial cells of what renal structure
collecting duct
prion is best described as a infectious
protein
where does blood go after leaving the small intestine
liver - detoxify
what does the liver remove when detoxify
ammonia, alcohol, and drugs
why do prokaryotes have a high degree of genetic adaptability and AR
short gen time, random mutations, and genetic recombination
we typically see ____ loop with estrogen and LH where additonal LH will cause additional production of estrogen which will trigger pit gland to LH
positive
when neuromodulator won’t influcen LH levels then estrogen will/not change
NOT
proteases are a _____ and what do they do
glycoprotein, they degrade proteins into smaller fragments
when ask how many net moles of ATP - and 6 x 1023 use avogrado constant
eggs and sperm are similar with
genome - NOT cell size, time require develop, not numbers produced
___ this protein forms cytosketal icrofilaments
actin
what product microtubules - also organizing center of it
centrosome - not kinetockers which are on the centromere of a chromosome - they only attach to microtubules
where in the human male reproductive system do gametes become motile and capable of fertilization
epididymis = sperm leave the testes and stored in epi where becomes motile, in the testes its non motile
using a higher voltage with the gels will only make proteins
migrate faster but not separate the subunits of homodimer
