This macromolecule is used as a source of energy.

The energy needed to start a chemical reaction.

The substance an enzyme acts on.

The attraction of substances of the same kind. (Molecule attracted to same type of molecule)

This scale measures how acidic or basic something is.

This macromolecule is non-polar, so it does not mix well with water. (Examples: Fats, oils, waxes)

A reaction in which energy is absorbed more than released.

Enzymes are this type of macromolecule.

Water is ___________, which means that part of the molecule are slightly positive and negative.

This word part means large.

This macromolecule consists of a long chain of amino acids.

This protein acts as a catalyst, decreasing activation energy and speeding up biochemical reaction.

The place where an enzyme attaches to its substrate.

Substances with a pH below 7.

This is an evenly distributed mixture of two substances.

Starch and sugar are examples of this macromolecule.

An explosion is an example of this type of reaction.

These factors effect enzyme activity.

Water sticking to a straw is an example of this type of attraction.

This is the term for double sugars such as sucrose.

Examples of this macromolecule are DNA and RNA.

The substances in a reaction that are going through the changes.
CO2 + H2O --> H2CO3

Enzymes are a type of _____________, a substance that decreases the activation energy of a reaction.

These bonds between molecules give water its properties.

Nucleic acids are made of smaller units called this.
