2. electron an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed
6. the electronegativity of the atoms will be equal
12. fat there is at least one double bond in the fatty acid chain and tends to be liquid from plants
14. complex the structure that results in the maximum energy point along the reaction path.
15. lipid monomer
18. a type of lipid that is made up of four interlocked rings of carbon called a steroid, only found in animal cells
19. a natural or artificial place where water is collected and stored for use
20. polysaccharides of glucose that serves as a form of energy storage in animals

1. fat lack double bonds between the individual carbon atoms and tends to be solid and from animals
3. reaction an action that releases heat, causing the temperature of the immediate surroundings to rise
4. monomers of nucleic acid
5. bond a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water
7. the electronegativity of the atoms will be different.
8. a fibrous substance consisting of polysaccharides, which is the major constituent in the exoskeleton
9. formed from glycerol and three fatty acid groups
10. the part of the metabolism responsible for breaking complex molecules down into smaller molecules.
11. the part which builds complex molecules from simpler ones
13. heat the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
16. reaction an action that absorbs heat and cools the surroundings
17. Fat a form of unsaturated fat associated with a number of negative health effects
