Bio Vocab Unit 2

3. Sphere of the earth, all soil and rocks on earth
4. Process of using light energy to make glucose, starts with CO2 and H2O and ends with C6H12O6 and O2
5. Organelle, site of steps 2 and 3 of (aerobic) cellular respiration
6. Type of organism than must eat other organisms to obtain energy
8. Organelle, site of photosynthesis
11. Describes a situation in which oxygen is present
13. Sphere of the earth, all living things on earth
14. Second step of aerobic cellular respiration, pyruvate is broken down NADH and FADH2 are made, released CO2
17. type of organism that is able to make it's own food, base of the food chain
18. Substances at the beginning of a chemical reactions, changed into products
20. Sphere of the earth, all the water on earth
21. Nutrient, forms the backbone for all macromolecules and living things
23. Nutrient, used in phosphates of nucleic acids, and phosphate lipids of membranes, often limited
25. First step of photosynthesis, uses sunlight to split H2O and make ATP and NADPH, O2 is released
26. type of organism that breaks down biotic compounds into abiotic compounds, recyclers

1. Sphere of the earth, all the glasses surrounding earth
2. Second step of anaerobic cellular respiration, 2 types include alcoholic and lactic acid
7. Third step of aerobic cellular respiration, NADH and FADH2 from earlier reactions are used to make 32 units of ATP
9. Substances created during a chemical reactions, made from reactants
10. Adenosine Diphosphate, uncharged energy storage molecule with 2 phosphates
12. Process of breaking down glucose to make ATP, starts with CO2 and H2O and ends with C6H12O6 and O2
15. Anything that has mass and takes up space, makes up everything
16. Adenosine Triphosphate, charged energy storage molecule with 3 phosphate groups
17. Describes a situation in which oxygen is NOT present
19. Pigment in chloroplasts, used to trap light energy during photosynthesis
22. Nutrient, used in proteins and nucleic acids, must be "fixed" for living things to use, often limited
24. First step of cellular respiration breaks down glucose into pyruvate, makes NADH
