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