Real AAMC stuff to review - CP

gas-liquid chromatography, the first peak to emerge will be:

the least polar, most volatile compound

standard atmospheric pressure is:

Atmosphere (atm) – 1 atm

Millimeters of mercury (mmHg or Torr) – 760 mmHg

Pascal (Pa) – 101,325 Pa

“Oxidation of self-assembled, micellular Compound 1 with iodine resulted in a solid material (Compound 2) that was stable to alkaline solutions (Equation 2)” this means:

S-S bonds

phosphorylation occurs the most efficiently with:

primary alcohols

Radioactive Decay

Voltaic Cell where does oxidation/reduction occur?

converging vs diverging lens

What is specific gravity (SG)?

Light wavelengths

Periodic table :)

ATP phosphates

What is the difference between diffusion and dispersion?

Diffusion:

• Movement of particles from high → low concentration

• Driven by random motion

• Goal: even distribution

• Example: perfume spreading in a room

Dispersion:

• Separation of waves (usually light) by wavelength

• Caused by different speeds of components

• Goal: separate components

• Example: rainbow from a prism

MCAT memory trick:

• Diffusion = “DIFFerence in concentration”

• Dispersion = “DISPersing light into colors”

Venturi Effect

How can you tell if a bond is a coordinate (dative) covalent bond?

**Coordinate covalent bond = covalent bond where BOTH shared electrons come from one atom.

How to spot it:

1. Look for an atom with a lone pair (common: N, O, S, halogens)

2. Look for an electron-deficient atom (common: H⁺, metal cation)

3. If the lone pair forms a bond without the other atom contributing electrons, it’s coordinate covalent

Visual trick: Draw an arrow → from the donating atom to the acceptor

Examples:

• NH₃ + H⁺ → NH₄⁺ (N donates lone pair)

• CO → Fe²⁺ (C donates lone pair to Fe²⁺)

Memory trick:

“Someone gives both their electrons → coordinate covalent”

ITC and CITC

• Understand what ITC measures – it detects the heat released or absorbed when a ligand binds a protein.

• Recognize how competition affects it (CITC) – a competitor reduces available binding sites, so injections of your ligand produce less heat.

• Translate experimental manipulations into outcomes – e.g., more competitor → fewer free sites → smaller measured ΔH → lower apparent binding constant Kapp​.
