| Questão | Responda |
| 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 | ATP is produced on the internal membranes of mitochondria and chloroplasts and that synthesis of ATP takes place by means of a flow of protons across these membranes down a concentration gradient through the enzyme ATP synthetase located in the stalked particles. This is called chemiosmosis. |
| Compare proton flow across mitochondrial and chloroplast memnranes | In mitochondria the protons flow across the inner membrane from the intermembrane space into the matrix. In chloroplasts the protons flow across the thylakoid membrane from the thylakoid space into the stroma.. |
| 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 |
