Energy Transformations and Cycles

6. Reactions that need oxygen to function
7. Sphere of Earth, all the soil and rocks on Earth
8. Pigment in chloroplasts, used to trap light energy during photosynthesis
11. Organelle:Site of steps 2 and 3 of aerobic respiration
14. Nutrient, used in the phosphates of nucleic acids and phospholipids of membranes, often limited
16. Substances created during a chemical reaction, made from reactants
17. Organisms that make their own food
19. Nutrient, used in proteins and nucleic acids,must be 'fixed' for living things to use, often limited
21. Second step of anaerobic respiration, 2 types include alcoholic and lactic acid
22. Nutrient, forms the backbone for all macromolecules in living things
23. Anything that has mass and takes up space, makes up everything
25. First step of photosynthesis, uses sunlight to split H2O and make ATP and NADPH
26. Type of organism that must eat other organisms to obtain energy

1. Type of organism that breaks down biotic compounds into abiotic compounds
2. Second step of aerobic respiration, pyruvate is broken down while NADH and FADH2 are made
3. Second step of photosynthesis, uses energy in ATP and NADPH to make glucose
4. Sphere of Earth, all the water on Earth
5. Reactions that don't need oxygen to function
6. Adenosine Diphosphate
9. Sphere of Earth, all of life on Earth
10. Organelle: Site of photosynthesis
12. Adenosine Triphosphate
13. Process of breaking down glucose to make ATP
14. Process of using light energy to make glucose
15. Sphere of Earth, all the gases on Earth
18. Substances at the beginning of a chemical reaction, changed into products
20. Third step of aerobic respiration , NADH and FADH2 are used to make 32 units of ATP
24. First step of aerobic respiration, breaks down glucose into pyruvate, makes some NADH
