Question	Answer
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
