Biology
Across
- 3. Nutrient, used in phosphates of nucleic acids and phospholipids of membranes, often limited
- 4. Adenosine diphosphate, uncharged energy storage molecule with 2 phosphates
- 5. Substance at the beginning of chemical reaction changed into products
- 11. Organelle - site of photosynthesis
- 12. Sphere of earth, all the soil and rocks on earth
- 15. site of steps 2 and 3 of aerobic cellular respiration
- 17. Adenosine triphosphate, charged energy storage molecule with 3 phosphorus groups
- 20. Describes a situation in which oxygen is present
- 21. used in proteins and nucleic acids, must be 'fixed' for living things to use, often limited
- 23. First step of aerobic respiration, breaks down glucose (ch1206) into pyruvate, make some nadh
Down
- 1. Sphere of earth, all living things on earth
- 2. Sphere of earth all water on earth
- 6. Sphere of earth, all the gases surrounding earth
- 7. Pigment in chloroplast used to trap light energy during photosynthesis
- 8. Process of breaking down glucose to make ATP starts with glucose and oxygen and ends with carbon dioxide and water
- 9. Second step of anaerobic respiration, two types include alcoholic and lactic acid
- 10. Substance created during a chemical reaction made from reactants
- 13. Process of using light energy to make glucose starts with carbon dioxide and water and ends with glucose and oxygen
- 14. Describes a situation in which oxygen is not present
- 16. forms the backbone for all macromolecules in living things
- 18. Second step of photosynthesis uses energy in ATP in NADPH to make glucose from CO2
- 19. Anything that has mass and takes up space, makes up everything
- 22. First step of photosynthesis, uses sunlight to split h2o and make atp and nadph, o2 is released
