Unit 2 Biology

1. Third step in aerobic respiration, NADH and FADH2 from early stages are used to make 32 units of ATP.
6. substances that are created during chemical reactions, made from reactants.
8. occurs in membranes in chloroplast, uses chlorophyll to capture light energy, energy used to split H2O to create O2 and excite electrons.
9. used by all living things to store and release energy. Powers reactions.
11. Sphere of earth, all water on earth.
13. the process of breaking down glucose to make ATP, starting with C6H12O6 and O2 ending in CO2 and H2O.
14. substances at the beginning of chemical reactions that are later changed to products.
16. a situation where oxygen is present.
17. organelle, holds steps 2 and 3 from the aerobic cellular respiration.

2. process of using light energy to make glucose, starts with CO2 and H2O and ends with C6H12O6 and O2.
3. First step in aerobic respiration and occurs in the cytoplasm. Breaks down glucose into pyruvate and makes some NADH.
4. a situation where oxygen is not present
5. doesn't need sunlight, located in stroma of chloroplast. Takes in CO2 to make glucose (C6H12O6). ATP and NADPH from light reaction to create C6H12O6 from CO2.
7. sphere of earth, all soil and rocks on earth.
9. use light energy to convert CO2 and H2O into high energy carbs (glucose) and oxygen.
10. second step of aerobic respiration, pyruvate is broken down while NADH and FADH2 are made, releases CO2.
11. eat autotrophs in order to get energy
12. anything that has mass and takes up space, makes up everything.
15. when ATP releases energy(phosphate) and the bond is broken this is what is made:
16. Sphere of the earth, all gases surrounding earth.
