Across
  1. 3. a type of lipid that is made up of four interlocked rings of carbon called a steroid, only found in animal cells
  2. 5. a fibrous substance consisting of polysaccharides, which is the major constituent in the exoskeleton
  3. 7. formed from glycerol and three fatty acid groups
  4. 9. an action that releases heat, causing the temperature of the immediate surroundings to rise
  5. 13. 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
  6. 17. 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. 18. the part which builds complex molecules from simpler ones
  8. 19. the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.
  9. 20. a form of unsaturated fat associated with a number of negative health effects
Down
  1. 1. polysaccharides of glucose that serves as a form of energy storage in animals
  2. 2. reaction an action that absorbs heat and cools the surroundings
  3. 4. the structure that results in the maximum energy point along the reaction path
  4. 6. lipid monomer
  5. 8. a natural or artificial place where water is collected and stored for use
  6. 10. lack double bonds between the individual carbon atoms and tends to be solid and from animals
  7. 11. monomers of nucleic acid
  8. 12. the electronegativity of the atoms will be equal
  9. 14. the electronegativity of the atoms will be different.
  10. 15. the part of the metabolism responsible for breaking complex molecules down into smaller molecules.
  11. 16. there is at least one double bond in the fatty acid chain and tends to be liquid from plants
