MCAT HIGH YIELD | TOP CONCEPTS & EXAM
REVIEW
When does pKa=pH? - answer ✔✔-when there are an equal amount of Hs and OHs
How does volume in a thermometer expand? - answer ✔✔-it must have a larger volume expansion
coefficient to fluctuate with temperature
Two amino acids linking together make a ____ bond - answer ✔✔-peptide
Fischer esterification - answer ✔✔-forms an ester (COOR)
involves reacting an acid and alcohol with a COOH to form an ester
a protecting group does what? - answer ✔✔-reduces nucleophilicity of the group that it is protecting
oxidizing agent - answer ✔✔-it oxidizes another species but becomes reduced itself in the process
In an electrochemical cell oxidation occurs at the _____ and reduction occurs at the _____. So electron
flow is from ____ to_____. - answer ✔✔-anode, cathode
anode to cathode
Eocell is calculated how? - answer ✔✔-E reduction potential at cathode- E reduction potential at anode
, charge on an cathode? - answer ✔✔-the charge is negative because it attracts cations
charge on an anode? - answer ✔✔-the charge is positive because it attracts anions
What is the molecular weight of each peptide bond formed? - answer ✔✔-18
Amino acids form in which direction? - answer ✔✔-amino (N terminus) to carboxyl (C terminus)
Equation for torque? - answer ✔✔-F*sin0*d (from the center fulcrum) or F*d (if the torque is
perpendicular)
Why might an electron configuration not fill like you might think it should? - answer ✔✔-it is more
stable filling the top one fulling and half filling the lower subshell (s)
Beta decay - answer ✔✔-an electron is released and a neutron is converted into a proton...the mass
number increases by one
Henderson-Hasselbalch equation - answer ✔✔-pH=pKa+log(conj base/acid)
log (1/10)
log(10/1) - answer ✔✔--1
1
Hydrofluoric acid+ calcium= - answer ✔✔-calcium fluoride-- highly insoluble and therefore precipitates
in the body and lower serum calcium in body
in splicing what is removed - answer ✔✔-introns are removed and exons are fused together to leave the
nucleus after further modification
