100
This organic polymer is made up of small molecules called amino acids and functions to do work in cells.
What are proteins?
100
This type of fatty acid contains carbon atoms are bonded to as many hydrogen atoms as possible and tend to be solid at room temperature.
What are saturated fatty acids?
100
This class of organic compounds include substances such as fat or oil and are used as a long-term energy molecule as well as a water resistant membrane.
What is a lipid?
100
The millions of organic compounds can be grouped into these four major types of compounds.
What are carbohydrates, lipids, proteins, and nucleic acids?
100
This type of fatty acids contain carbon atoms not bonded to as many hydrogen atoms as possible and tend to be liquid at room temperature.
What are unsaturated fatty acids?
200

This refers to anything that has mass and takes up space.

What is Matter

200
Water is known to have a difference in electrical charge between different parts of the same molecule, this water is this type of molecule.
What is a polar molecule?
200

These are positively charged particles that determine an atom's identity

What are protons?

200

This number is found by adding the protons and the neutrons found in an element's nucleus.

What is Atomic mass or mass number?

200

An atom that has gained or lost an electron and is no longer neutral is called this

What is an ion?

300
This class of organic compounds include sugars or starches, and are used to store energy.
What are carbohydrates?
300
Acidity is measured on this scale.
What is the pH scale?
300
A solution with a pH lower than 7 is called this.
What is an acid?
300

A high concentration of hydroxide ions in a solution is known as this.

What is basic?

300
The type of bond that forms between polar molecules like water is known as this.
What is a hydrogen bond?
400

A substance that is an input to a chemical reaction is called this

What are reactants?

400
These are proteins that speed up chemical reactions in cells in temperatures that are far below that of burning flesh.
What are enzymes?
400
A solution with a pH higher than 7 is called this.
What is a base?
400
This class of organic polymers include molecules such as DNA or RNA, are built of small units called nucleotides, and serve as information molecules.
What are nucleic acids?
400
This organic polymer is a complex carbohydrate that forms when simple sugars bind together in a chain and serve as energy and structural molecules.
What are polysaccharides?
500

 a substance that forms as a result of a chemical reaction is called this. 

What is a product?

500
The sum of all the biochemical reactions in an organism is called this.
What is metabolism?
500

These are particles that carry no charge and determine the atom's mass.

What are neutrons?

500
The energy needed to start a chemical reaction is called this.
What is activation energy?
500

This term represents the attraction between two or more molecules of water

What is cohesion?
