1. Atom
The smallest units of matter; combines with other atoms to form molecules. Both living and nonliving things are made from atoms.

2. Molecule
Two or more atoms joined together. Can be made from the same atoms or different atoms.

3. Molecule made entirely from the same type of atom.
Pure Element
Molecule made entirely from the same type of atom.

4. Molecules made from different atoms.
Compound
Molecules made from different atoms.

5. A compound that contains carbon atoms.
Organic Compound
A compound that contains carbon atoms.

6. An element found in all living things
Carbon
An element found in all living things

7. A molecule that contains carbon along with other elements
Organic Compound
A molecule that contains carbon along with other elements

8. A small molecule that joins together with other monomers
(mono = single)

9. A large molecule made from many monomers joined together
Polymer/Macromolecule
A large molecule made from many monomers joined together
(poly = many)

10. The process of joining monomers together to form polymers
Polymerization
The process of joining monomers together to form polymers

11. Carbohydrate
An organic compound that living things use as their main source of energy

12. Monomer of carbohydrates
Glucose
Monomer of carbohydrates

13. Starch
A carbohydrate polymer used by plants to store energy; made from glucose monomers

14. Another carbohydrate polymer; used by plants for structure
Cellulose
Another carbohydrate polymer; used by plants for structure

15. Lipid X
An organic compound that living things use to store energy; not made from monomers

16. Nucleic Acid
An organic compound that stores and transmits genetic information (DNA)

17. Monomer of nucleic acid (DNA)
Nucleotide
Monomer of nucleic acid (DNA)

18. Protein
An organic compound that gives strength and structure, fights disease, and speeds up chemical reactions

19. Amino Acid
Monomer of protein

20. A special protein that speeds up the rate of chemical reactions
Enzyme
A special protein that speeds up the rate of chemical reactions

21. Chemical Reaction + =
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
Process in which reactants change into products; bonds between atoms change, creating a new substance.

22. + Reactants Substances that enter into a chemical reaction.
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
Substances that enter into a chemical reaction.

23. Product New substance(s) created during a chemical reaction.
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
New substance(s) created during a chemical reaction.

24. Activation Energy
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
The amount of energy needed to get a reaction started. High activation energy = slow, difficult reaction.

25. Enzyme
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
A protein that speeds up (catalyzes) chemical reactions by lowering the activation energy.

26. Substrate Substance an enzyme acts upon and changes.
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
Substance an enzyme acts upon and changes.

27. Catalyze To speed up a chemical reaction.
A chemical reaction is a process that changes one set of chemicals into another set of chemicals. The coke/mentos explosion is a type of chemical reaction.
To speed up a chemical reaction.
