3. fat lack double bonds between the individual carbon atoms and tends to be solid and from animals
6. the electronegativity of the atoms will be equal
12. the part of the metabolism responsible for breaking complex molecules down into smaller molecules.
13. a natural or artificial place where water is collected and stored for use
15. formed from glycerol and three fatty acid groups
16. Fat a form of unsaturated fat associated with a number of negative health effects
20. complex the structure that results in the maximum energy point along the reaction path.

1. 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
2. polysaccharides of glucose that serves as a form of energy storage in animals
4. reaction an action that absorbs heat and cools the surroundings
5. 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
7. fat there is at least one double bond in the fatty acid chain and tends to be liquid from plants
8. the electronegativity of the atoms will be different.
9. lipid monomer
10. monomers of nucleic acid
11. a type of lipid that is made up of four interlocked rings of carbon called a steroid, only found in animal cells
14. reaction an action that releases heat, causing the temperature of the immediate surroundings to rise
17. the part which builds complex molecules from simpler ones
18. heat the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
19. a fibrous substance consisting of polysaccharides, which is the major constituent in the exoskeleton
