2.4 Cell Processes

6. Respiration that requires oxygen to produce energy.
8. The process by which plants convert light energy into chemical energy in the form of glucose.
9. Passive transport of molecules across a membrane using protein channels.
11. The molecule that stores and provides energy for cellular processes.
12. The organelle where cellular respiration occurs.
13. The jelly-like substance in cells where chemical reactions occur.
14. The movement of molecules against a concentration gradient using energy (ATP).
16. A membrane that allows certain molecules to pass through while blocking others.

1. The complex formed when an enzyme binds to its specific substrate.
2. Respiration that occurs without oxygen and produces less energy.
3. The passive movement of molecules from a region of high concentration to low concentration.
4. The movement of water molecules across a semi-permeable membrane from high to low water potential.
5. The organelle where photosynthesis occurs in plant cells.
7. The green pigment in chloroplasts that absorbs light for photosynthesis.
10. The process by which cells release energy from glucose.
15. A biological catalyst that speeds up chemical reactions in cells.
