AAMC FL2 Chem/Phys Missed Concepts Flashcards
Physics
Light Energy Equation
E = hf = hc/λ
h = 6.62 x 10^-34 Js
c = 3 x 10^8 m/s
Units: eV = J
Biochemistry
kcat Equation
Kcat = Vmax/[E]
Units: M/s/M = s^-1
Physics
Absorption of UV light by organic molecules always results in
electronic excitation (bond breaking, ionization/bond vibrations can result)
Physics
Half-life of a radioactive material
the time it takes for half of all the radioactice nuclei to decay into their daughter nuclei
Biochemistry
What kind of curve is cooperative?
sigmoidal
Physics
Oxygen Pressure Equation
Pair = P + 1/2pv^2
P = oxygen static pressure
Physics
Venturi Effect
Static pressure of the air is larger than the static pressure of the oxygen in flow
This causes air to enter a mask
Biochemistry
Triacylglycerols
- neutral storage protein
- 3 fatty acids ester-linked to a single glycerol
General Chemistry
Anode =
Cathode =
anode = oxidation = loss of e- = increased oxidation state
cathode = reduction = gain of e- = decreased oxidation state
Physics
Boyle’s Law
pressure and volume of a gas have an inverse relationship when temperature is constant
P1V1 = P2V2
Physics
Charle’s Law
Describes how gases tend to expand when heated
Volume is directly proportional to absolute temperature, if pressure remains constant
V1/T1 = V2/T2
General Chemistry
Heisenberg Uncertainty Principle
there is inherent uncertainty in the act of measuring a variable of a particle
applied to the position and momentum of a partical
General Chemistry
Lewis Base
donates non-bonding electron pair forming a covalent interaction
General Chemistry
Lewis Acid
nonbonding electron pair acceptor
General Chemstry
Function of a Catalyst
increase the rate of a chemical reaction
increase the amount of product per unit time
General Chemistry
Coordinate Covalent Bond
interaction between a metal cation and electron pair donor
General Chemistry
Coordinate ionic bond
one atom donates its electrons to form the bond
General Chemistry
Covalent Bond
sharing of electrons to form electron pairs between atoms
General Chemistry
Ionic Bond
electrostatic interaction between oppositely charged ions
General Chemistry
coordination number (ligancy)
the number of atoms, ions, or molecules bonded to the atom in question
General Chemistry
Oxidation number
when an atom, molecule, or ion loses one or more electrons in a chemical reaction
oxidation = increased oxidation number
reduction = decreased oxidation number
Biochemistry
Henderson-Hasselbach Equation
pH = pka + log ([base]/[acid])
Biology
systolic pressure
the first sound of blood flow that can be heard once the pressure exerted by the inflatable cuff falls below the pressure in the artery
higher number
General Chemistry
Hess’s Law
the total enthalpy change for the reaction is the sum of all changes
Physics
At STP what is the volume of any gas?
22.4 L/mol
Physics
Average Power
P = PE/time = mgh/t
Physics
work (elastics/springs)
W = 1/2kx^2
Sound
Intensity Ratio
dBf = dBi +10log(If/Ii)
(dBf - dBi)/10 = log(If/Ii)
10^(dBf - dBi)/10 = If/Ii
Physics
Negative Focal Length = [–] lens
diverging
* form virtual and reduced images of objects situated at distances larger than the focal length
Physics
Energy Conversions through a battery powered resitive circuit
Chemical to electrical to thermal
