Label each cell with the energy source it needs to perform its functions

Cell Function | Energy Source

-------------------------------
1. Muscle contraction | ATP (Adenosine triphosphate)
2. Protein synthesis | ATP (Adenosine triphosphate)
3. Active transport | ATP (Adenosine triphosphate)
4. DNA replication | ATP (Adenosine triphosphate)
5. Nerve impulse | Sodium and potassium ions (from ion gradient maintained by ATP-dependent sodium-potassium pump)
6. Photosynthesis | Sunlight (converted into chemical energy in the form of ATP and NADPH)
7. Respiration | Glucose (oxidized to produce ATP through cellular respiration)
8. Cell division | ATP (Adenosine triphosphate)
9. Endocytosis | ATP (Adenosine triphosphate)
10. Protein folding | ATP (Adenosine triphosphate)
11. Protein degradation | ATP (Adenosine triphosphate)
12. Enzyme catalysis | ATP (Adenosine triphosphate)
13. Cell signaling | ATP (Adenosine triphosphate)
14. Ion channel transport| ATP (Adenosine triphosphate)
15. DNA transcription | ATP (Adenosine triphosphate) and nucleotide triphosphates
