Miscellaneous
G protein type for respective receptors
“KISS and KICK till you’re SICK of SEX” (QISS and QIQ till you’re SIQ of SQS):
This gives the G-protein type (Gq, Gi, or Gs) for all the receptors. Receptors are in alphabetical order:
alpha1=Q alpha2=I
beta1=S beta3=S
M1=Q M2=I M3=Q
D1=S D2=I
H1=Q H2=S V1=Q
V2=S
Golgi complex: functions
“Golgi Distributes A SPAM“:
Distributes proteins and lipids from ER Add mannose onto specific lysosome proteins
Sulfation of sugars and slected tyrosine Proteoglycan assembly
Add O-oligosugars to serine and threnonine Modify N-ologosugars on asparagine
Metabolic acidosis (normal anion-gap): causes
With hyperkalemia: RAISE K+:
RTA type 4
Aldosterone or mineralocorticord deficiency Iatrogenic: NH4Cl, HCl
“Stenosis”: obstructive uropathy Early uremia
With hypokalemia: ReDUCE K+:
Renal TA type 1 and 2 Diarrhoea Urine diversion into gut
Carbonate anhydrase inhibitor Ex-hyperventilation
Metabolism sites
“Use both arms to HUG“:
Heme synthesis
Urea cycle Gluconeogenesis
These reactions occur in both cytoplasm and mitochondria.
Na/K pump action
(Sing loudly to the chorus of “Kiss Him Goodbye”): “Na, Na, Na — out! Na, Na, Na — out! K, Kgoes…inside!”
Action of pump is 3 Na out and 2 K in
Na/K pump: concentrations of Na vs. K on inside/outside of cell, pump action, number of
molecules moved
HIKIN‘:
There is a HIgh K concentration INside the cell.
From this can deduce that the Na/K pump pumps K into cell and Na out of cell.
Alternatively: When I was learning this pump (circa 1992), a band that was “in” was Kris Kross, and a band that was “out” was “Sha Na Na Na“:
So pump moves K K (2 K) in and Na Na Na (3 Na) out.
Sadly, as infectious as their debut album was, Kris Kross can really no longer be classed as “in”.
Na+/K+ pump: movement of ions and quantity
K+ and in each consist of 2 characters, so so 2 K+ are pumped in.
Na+ and out each consist of 3 characters, so 3 Na+ are pumped out.
Tangier’s disease: hallmark
“Tangierene tonsils”:
Hallmark is large orange tonsils.
Important clinical note: there is no increased risk of atherosclerosis, just like eating tangerenes.
Cell division
“People Meet And Talk.”
Prophase
Metaphase Anaphase
Telophase
