100
The force that holds substances together.
What is a chemical bond?
200
A substance that lowers the activation energy needed to start a chemical reaction.
What are catalysts?
200
A macromolecule composed of carbon, hydrogen, and oxygen with a ratio of one oxygen and two hydrogen atoms for each carbon atom.
What are carbohydrates?
200
An example of a nucleic acid that stores genetic information.
What is DNA
200
The attraction/force between the positive and negative regions of molecules that hold them together.

300
Positively charged particles.
What are protons?
300
The reactants that bind to the enzyme.
What are substrates?

400
Negatively charged particles
What are electrons?
400
Specific location where a substrate binds on an enzyme.
What are active sites?
400
These things make up nucleotides.

What is an ion?
500
Particles that have no charge
What are neutrons?
500
This complex helps to break bonds in the reactants and form new ones, changing the substrate into products.
