Biology-crossword
Across
- 5. organelle that is the site of ATP (energy) production, (converts glucose into ATP)
- 6. An organelle found only in plant and algae cell, site of photosynthesis occurs
- 8. organism that obtains energy by eating animals
- 10. reactions of photosynthesis that use energy from light to produce ATP and NADPH, also produces O2
- 11. Only 10% of the energy in one trophic level gets passed onto the next trophic level
- 12. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy, site of the light reactions
- 13. 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)
- 16. organism that obtains energy from the foods it consumes; also called a consumer
- 17. electron carrier that provides high-energy electrons for photosynthesis
- 18. the breakdown of glucose by enzymes, releasing energy and pyruvate, 1st step in cellular respiration, takes place in the cytoplasm
- 20. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water (Calvin/Dark reaction)
- 22. main energy source that cells use for most of their work, made up of adenosine, ribose and 3 phosphates
- 23. organism that eats dead organic matter
- 24. stacks of thylakoids
- 25. Organisms that make their own food
- 26. organism that breaks down and obtains energy from dead organic matter
Down
- 1. An organism that eats only plants
- 2. 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.
- 3. An organism that eats other organisms
- 4. one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules
- 6. 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, steps include gylcolosis, krebs cycle and electron transport chain
- 7. the passage of energy through the components of the ecosystem
- 9. reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars, also called dark reaction, no light needed, creates NADP+ and ADP, takes place in the stroma
- 14. a cluster composed of hundreds of chlorophyll molecules and accessory pigments used to harvest light molecules for photosynthesis
- 15. green pigment in plants that absorbs light energy used to carry out photosynthesis, found in the thylakoid of the chloroplast
- 19. An animal that eats both plants and animals
- 21. a lower-energy molecule that can be converted into ATP by the addition of a phosphate group, made up of adenosine, ribose and 2 phosphates
