100

The three basic subatomic particles that make atoms.

What are protons, neutrons, and electrons?

100

Also known as “dihydrogen monoxide”, is it a molecule composed of two hydrogen atoms bonded to a single oxygen atom.

What is water?

100

These molecules include simple sugars and polysaccharides such as glucose, starch, and cellulose.

What are carbohydrates?

100

This molecule, which can be harmful if present in the human body in large amounts, wedges among phospholipid tails and typically reduces permeability by tightening lipid packing.

What is cholesterol?

100

A running gag of the sketches is that this recurring Jeopardy! category appears every time yet famously goes unpicked.

What is “Potent Potables”?

200

The chemical property that measures an atom's ability to attract electrons in a chemical bond.

What is electronegativity?

200

The property of water's surface that allows it to resist external forces, caused by the polar nature of water molecules being attracted to each other.

What is surface tension?

200

With hydrophilic heads and hydrophobic tails, these molecules are the principal structural components of cell membranes.

What are phospholipids?

200

Movement of polar solutes down their gradient through a membrane channel or carrier without expending cellular energy.

What is facilitated diffusion?

200

Darrell Hammond’s most infamous impression in “Celebrity Jeopardy!” was this Scottish movie icon who became Trebek's on-screen nemesis.

Who is Sean Connery?

300

These are different forms of the same element that have the same number of protons, but different numbers of neutrons, giving it a different atomic mass number.

What are isotopes?

300

By combining cohesion among water molecules with adhesion to surfaces, this process lets water climb narrow tubes in plants.

What is capillary action?

300

Non-covalent attractions between this element, already covalently bonded to another highly electronegative atom, play a crucial role in stabilizing the secondary structures of proteins.

What are hydrogen bonds?

300

Placing an animal cell in this kind of solution causes net water loss and cellular shrinkage.

What is a hypertonic solution?

300

This SNL spin on the format featured Tom Hanks as “Doug,” a MAGA-hat-wearing contestant whose answers found surprising overlap with the other players.

What is “Black Jeopardy”?

400

Two molecules that differ only by a single H+ ion, and trade that ion between each other to form a weak acid and a weak base.

What is a conjugate acid–base pair?

400

Because escaping the liquid phase requires breaking many hydrogen bonds, water has an unusually high value for this property, exploited in sweating.

What is the 'heat of vaporization' point?

400

This covalent bond forms the sugar–phosphate backbone in DNA and RNA by bonding the 5-phosphate group of one nucleotide to the 3-hydroxyl group of the next nucleotide.

What is a phosphodiester bond?

400

In animal cells, this ATP-powered membrane protein maintains critical electrochemical gradients necessary for nerve impulse transmission, muscle contraction, and cell volume regulation by exporting Na⁺ and importing K⁺.

What is the sodium–potassium pump?

400

According to Norm Macdonald’s behind-the-scenes account of SNL40, this comedy legend declined to portray Bill Cosby in the sketch.

Who is Eddie Murphy?

500

The negative logarithm of an acid’s dissociation constant, this value gets smaller as acid strength increases.

OR

The pH at which a specific acid is 50% dissociated into its conjugate base and a H+ ion.

What is pKa?

500

Water’s exceptional ability to dissolve salts stems partly from its very high value for this electrical property, which causes it to weaken the electrostatic attraction between the ions holding the salt crystals together.

What is the dielectric constant?

500

Formed between two cysteine side chains, these covalent bonds help lock in a protein’s tertiary structure.

What are disulfide bonds?

500

By freezing and cracking membranes and viewing the split surface with SEM, this preparation method revealed embedded proteins and helped replace the “sandwich” model with the fluid–mosaic model to describe the phospholipid bilayer of cell membranes.

What is freeze-fracture electron microscopy?
