importance of ATP

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	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
