100

The three parts of an atom and their charges are

proton (+), electron (-), neutron (neutral)

100

A process that changes, or transforms, one set of chemicals into another.

chemical reaction

100

The four organic macromolecules.

carbohydrates, lipids, proteins, nucleic acids

100

A single unit/sub-unit of a polymer

Monomer

100

Biological buffers keep most cells around this pH

Neutral/6.5-7.5

200

Name and define the two components of a solution

solute: substance that is dissolved solvent: substance in which the solute dissolves

200

the energy needed to get a reaction started

activation energy

200

Functions of this macromolecule include structure, repair and speeding up reactions- almost everything in the body

200

Macromolecules are primarily held together by this type of bond

Covalent bond

200

Has a pH of less than 7

acid

300

Name and define the two types of mixture

Heterogeneous mixture - unevenly mixed

No

400

A molecule with a partially charged positive end and a partially charged negative end

polar molecule

400

This bond joins two or more molecules together by transferring electrons Ex. NaCl

ionic bond

400

This macromolecule stores information within a cell

Nucleic acid

400

Isotopes

500

Joins two or more atoms together by sharing electrons, ex. CO2

covalent bond

500

What is the relationship between enzymes and activation energy?

Enzyme decrease the activation energy during chemical reactions.
