Across
  1. 2. 2nd step of photosynthesis, no light needed
  2. 6. nutrient, used in phosphates of nucleic acids and phospholipids of membranes, often limited
  3. 7. nutrient, used in proteins and nucleic acids, must be "fixed" for living things to use, often limited
  4. 10. pigment in chloroplasts, used to trap light energy during photosynthesis
  5. 12. 3rd step of aerobic respiration, makes 32 units of ATP
  6. 13. charged energy storage molecule with 3 phosphorous groups
  7. 14. describes a situation in which oxygen is not present
  8. 15. first step of aerobic respiration, breaks down glucose into pyruvate, makes some nadph
  9. 16. describes a situation in which oxygen is present
  10. 17. 2nd step of anaerobic respiration, 2 types
Down
  1. 1. process of breaking down glucose to make ATP
  2. 3. organelle, site of steps 2 and 3 of aerobic cellular respiration
  3. 4. second step of aerobic repsiration
  4. 5. process of using light energy to make glucose
  5. 8. first step of photosynthesis, uses sunlight to split water and make ATP and nadph, oxygen is released
  6. 9. organelle, cite of photosynthesis
  7. 10. nutrient, forms the backbone for all macromolecules in living things
  8. 11. type of organism that breaks down biotic compounds into abiotic compounds, recycles
  9. 13. Uncharged energy storage molecule with 2 phosphates
  10. 18. anything that has mass and takes up space, make sup everything
