500

Describe where the protons, neutrons, and electrons are in an atom?

In an atom, protons and neutrons cluster together at the center, which is called the nucleus. Electrons orbit around the nucleus.

Changes in matter

100

What is the definition of phase?

One of three forms - solid, liquid, or gas

200

What is the definition of physical change?

A change that affects the appearance but not the chemical makeup of a substance

300

When you freeze water, are you causing a chemical change or a physical change?

Physical change

400

What is the definition of semipermeable membrane?

A membrane that allows some molecules to pass through but does not allow other molecules to pass through.

500

What's the difference between diffusion and osmosis?

Diffusion all molecules can move freely (water level doesn't change) whereas osmosis there is a semipermeable membrane so only some molecules can pass (water level raises on side of higher concentration).

Carbohydrate

100

What's the strongest - a single, double, or triple bond?

Triple bond

200

How do you break down carbohydrates into smaller pieces?

Hydrolysis

300

How do you build up polysaccharides?

Dehydration Reaction

400

What's the difference between monosaccharide, disaccharide, and polysaccharide?

Mono - one

Di - two

Poly - many

500

Which are carbohydrates?

PH₂, CO₂, C₆H₁₂O₆, C₅H₁₀O₅

Carbohydrates only have CHO, so C₆H₁₂O₆, C₅H₁₀O₅

Proteins/enzymes

100

What are proteins made up up?

Amino acids

200

What is most acidic?

pH of 1.5

300

What determines the properties of a protein?

The type and order of amino acids

400

What are enzymes and what are they used for?

Enzymes are a special class of proteins that are used as catalysts.

500
