Across
- 6. an organism that cannot make their own food and must feed on other organisms for energy or nutrients
- 7. an organelle that transforms energy stored in food molecules; site of cellular respiration
- 10. also known as Kreb cycle; series of reactions in cellular respiration that break down glucose and produce ATP in the mitochondria
- 12. the first stage in cellular respiration; a series if chemical reactions in the cytoplasm of a cell that breaks down glucose
- 14. energy storing molecule that can be used quickly and easily by cells
- 15. phase of photosynthesis where simple sugars (glucose) are formed from carbon dioxide using the ATP from light reaction
Down
- 1. an organism that use energy from the sun or energy stored in chemical compounds to make own nutrients
- 2. occurs after glycolysis if there is no oxygen present; either lactic acid or alcoholic
- 3. an organelle that contains pigments and captures light energy so it can convert it into chemical energy; site of photosynthesis
- 4. chemical process where mitochondria breaks down food molecules to produce ATP
- 5. process which autotrophs trap energy from sunlight with chlorophyll and use the energy to convert carbon dioxide and water into simple sugars.
- 8. chemical reactions that do require oxygen
- 9. phase of photosynthesis where light energy is converted to chemical energy in the form of ATP (splits water)
- 11. pigment that is found in plant's and some protist's organelles and absorbs light
- 13. chemical reactions that do not require oxygen
