| Frage | Antworten |
| What is ATP | Adenosine Triphosphate Universal energy carrier in all living cells |
| Where is ATP produced | In the internal membranes of mitochondria and chloroplasts |
| How is ATP synthesised | Involves ATP synthetase- an enzyme embedded in cellular membranes ATP synthetase phosphorylates ADP to form ATP as protons flow through it. |
| Compare proton flow across mitochondrial and chloroplast memnranes | mitochondria-H+ flow from intermembrane space into matrix across the inner membrane chloroplast- H+ flow from thylakoid space into stroma across the thylakoid membrane. |
| Define chemiosmosis | The synthesis of ATP through the movement of protons down their electrochemical gradient across a semi permeable membrane, catalysed by ATP synthetase |
| Potential energy associated with excited electrons is coupled to the active transport of H+ across the membrane by protein pumps |
