Biology Unit Two

3. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide, takes place in the mitochondria, produces ATP and NADH
9. The movement of phosphorus atoms from rocks through the biosphere and hydrosphere and back to rocks.
11. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy, site of the light reactions
13. process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches steps include: capture light, light dependent reactions, calvin cycle.
15. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water (Calvin/Dark reaction)
17. A process used by yeast cells and some bacteria to produce carbon dioxide and ethyl alcohol
19. The conversion of pyruvate to lactate with no release of carbon dioxide

1. Produced by fermentation and oxidation of natural carbohydrates is called vinegar
2. Transport Chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP, takes place in the mitochondria, produces the most ATP of any of the processes (34 ATP)
4. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen, takes place in plants and animals, happens in 3 processes
5. the passage of energy through the components of the ecosystem
6. An organelle found only in plant and algae cell, site of photosynthesis occurs
7. organism that obtains energy from the foods it consumes; also called a consumer
8. Organisms that make their own food
10. reactions of photosynthesis that use energy from light to produce ATP and NADPH, also produces O2
12. respiration Respiration that does not require oxygen
14. organelle that is the site of ATP (energy) production
16. Process by which cells release energy in the absence of oxygen
18. respiration Respiration that requires oxygen
