Across
- 3. Forms the outer boundary of cell and is selectively permeable due to its structure
- 5. A negatively charged particle that has very little mass and move around the nucleus of an atom
- 7. A molecule used for short-term energy storage
- 9. Mathematical expression of relative H+ concentration in a solution
- 10. A molecule that has many different functions in living things and are made of monomers called amino acids
- 12. A process that uses energy to remove a lot of material out of the cell
- 13. Multicellular organism
- 14. The minimum energy required to start a chemical reaction
- 16. The active site of the enzyme has been destroyed which causes the enzyme activity to fail
