Across
- 2. involves the breaking of many of the weak linkages, or bonds
- 3. Any of the tiny blood vessels that connect the smallest arteries to the smallest veins
- 8. passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration.
- 9. a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs.
- 10. A membrane that is permeable to the small molecules of water and certain solutes but does not allow the passage of large solute molecules
- 12. The specific region of an enzyme where a substrate binds and catalysis takes place or where a chemical reaction occurs.
- 13. the movement of water or another solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration
- 14. tiny sacs within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstream
Down
- 1. the process of particles, moving through a solution or gas from an area with a higher number of particles to an area with a lower number of particles
- 4. movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
- 5. the gills of an animal, most typically an amphibian, that are exposed to the environment
- 6. A minute blind-ended lymph vessel that occurs in each villus of the small intestine.
- 7. When an object/cell is very small, it has a large surface area to volume ratio, while a large object/ cell has a small surface area to volume ratio.
- 11. Proteins are made from these long chains
