Across
- 1. Molecule an enzyme acts upon.
- 4. Bulk transport out of the cell.
- 6. Bulk transport into the cell.
- 7. Cell division producing two genetically identical daughter cells.
- 9. Phase where cell grows and replicates DNA (
- 12. Change in enzyme structure (due to heat/pH) causing it to lose function.
- 13. Site of photosynthesis, contains chlorophyll.
- 14. Respiration without oxygen, low ATP yield.
- 19. Carbon dioxide is converted to glucose (Calvin Cycle/Stroma).
- 21. Specialized structures within a cell (e.g., mitochondria, chloroplast).
- 23. Resource in short supply that limits the rate of a reaction (e.g., light,
- 27. Process of copying DNA before division.
- 28. Semi-permeable barrier controlling movement of substances in/out of the cell.
Down
- 2. Biological catalyst, usually a protein, speeding up reactions.
- 3. Diffusion of water across a semi-permeable membrane.
- 5. Site of aerobic respiration.
- 8. Each new DNA molecule contains one original and one new strand.
- 10. Minimum energy needed to start a chemical reaction.
- 11. Energy carrier molecule ["energy currency"].
- 15. Specific region on an enzyme where the substrate binds.
- 16. Energy from light splits water.
- 17. Respiration using oxygen to break down glucose, producing high ATP yield.
- 18. Green pigment absorbing light energy.
- 20. First stage of respiration, occurs in cytoplasm.
- 22. Passive movement of particles from high to low concentration.
- 24. Movement of molecules against a concentration gradient, requiring
- 25. Division of the cytoplasm.
- 26. Formed when ATP loses a phosphate, releasing energy.
