Honors Biology Unit 2 Vocabulary

3. Describes a situation in which oxygen is present
6. Substances at the beginning of a chemical reaction, changed into products
7. Sphere of earth, all the gases surrounding earth
9. Organelle, site of steps 2 and 3 of aerobic cellular respiration
10. First step of aerobic respiration, breaks down glucose into pyruvate, makes NADH
12. Pigment in chloroplasts, used to trap light energy during photosynthesis
13. Nutrient used in proteins and nucleic acids, limited
14. Substances created during a chemical reaction, made from reactants
16. Adenosine Diphosphate, uncharged energy storage molecule with 2 phosphates
18. Type of organism that breaks down biotic into abiotic
20. Second step of Anaerobic respiration, 2 types: alcoholic and lactic acid
23. Third step of aerobic respiration, NADH and FADH are used to make 32 ATP
24. Describes a situation in which oxygen is not present
25. Nutrient, used in phosphates of nucleic acids and phospholipids of membranes, often limited
26. Process of using light energy to make glucose, starts with CO2 and H2O, and with C6H12O6 and O2
27. Sphere of earth, all the water on earth

1. Process of breaking down glucose to make ATP, starts with glucose, ends with carbon dioxide and water.
2. Second step of photosynthesis, uses energy in ATP and NADH to make glucose from Carbon Dioxide
4. Organelle, site of photosynthesis
5. Nutrient, forms the backbone of all macromolecules
8. Sphere of earth, all the soil and rocks on earth
11. First step of photosynthesis, uses sunlight to split H2O and ATP and NADH, O2 is released
15. Adenosine Triphosphate, charged energy storage molecule
16. Type of organism that is able to make it's own food
17. Sphere of earth, all the soil and rocks on earth
19. An organism that eats other organisms for energy
21. Anything that has mass and takes up space
22. Second step of aerobic respiration, pyruvate is broken down while NADH and FADH are made, release carbon dioxide
