Across
- 1. Membrane surrounded component of a eukaryotic cell with a specialized function.
- 4. Substance that forms from joining many small molecules.
- 10. The process by which molecules pass through a cell membrane using special proteins called transport proteins.
- 11. The process during which a cell's vesicles release their contents outside the cell.
- 12. Large macromolecule that does not dissolve in water.
- 13. A long chain of amino acid molecules; contains carbon, hydrogen, nitrogen, and sometimes sulfur.,
- 14. The movement of substances through a cell membrane without using the cell's energy.
- 15. A macromolecule made of one or more sugar molecules, which are composed of carbon, hydrogen, and oxygen; usually the body's major source of energy.
Down
- 2. A macromolecule that forms when long chains of molecules called nucleotides join together.
- 3. The movement of substances through a cell membrane using the cell's energy.
- 5. The process during which a cell takes in a substance by surrounding it with a cell membrane.
- 6. The diffusion of water molecules only through a membrane.
- 7. A series of chemical reactions that convert light energy, water, and carbon dioxide into the food energy molecule glucose and gives off oxygen.
- 8. A series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP.
- 9. The movement of substances through a cell membrane without using the cell's energy.
