AAMC FL 3 Flashcards
(39 cards)
pOH calculation from pH
pH + pOH = 14
cholesterol stucture
4 fused rings
period
peak to peak or trough to trough
activation energy
transition state energy - reactant energy
thermodynamic stability
can determine from heat of combustion; Thermodynamic stability occurs when a system is in its lowest energy state, or chemical equilibrium with its environment.
aldol condensation
enol form of one aldehyde performs nuc attack on carbonyl of second aldehyde or ketone –> an aldehyde and an alcohol one carbon apart
dehydration –> a double bond btween the middle carbon and former alcohol (alpha, beta unsaturated aldehyde)
porphyrin
5 sided heterocycle with N and DB opposite nitrogen
pH and pI relationship
if pH > pI –> -
if pH < pI –> +
capacitance
capacitance = charge/voltage
Energy stored by Capacitors
U = 1/2QV = 1/2CV^2 = 1/2Q^2/C
proton exchange
occurs between lone pairs on elements and water in aqueous solution; implications for labeling
how to tell if something is a redox reaction
do the oxidation numbers for all the elements involved; if changed, its a redox reaction
amu
one molecule oxygen has is 16 amu
and
one mole of oxygen has a mass of 16 g
property of waves not affected by medium
frequency
resistivity
the inverse of conductivity
volume flow rate
cross sectional area * fluid speed
purines vs pyrimidines
A G // CUT
apoptosis
blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay
convergent vs divergent evolution
convergent evolution - organisms not closely related independently evolve similar traits bc similar environment
divergent evolution - speciation results; occurs when one species diverges into multiple descendant species
restriction enzymes
need palindromic sequences ie. CCCGGG
more contractile force?
any increase in intracellular calcium does this
metabolic consequences of starving
Dramatic increases of glucagon and catecholamines; tissues rely on fatty acids
ETC complexes
I - NADH dehydrogenase
II - succinate dehydrogenase
III - CoQH2-cytochrome c reductase
IV - cytochrome c oxidase
Krebs substrates mnemonic
Citrate Is // isocitrate Krebs // alpha ketoglutarate Starting // succinyl CoA Substrate // succinate For // fumarate Making // malate Oxaloacetate
