Importance Of ATP Flashcards
1
Q
What is ATP?
A
Adenosine Triphosphate
Universal energy carrier found in all living cells
2
Q
Where is ATP produced?
A
It is synthesised on the internal membrane of the mitochondria and chloroplast
3
Q
How is ATP synthesised?
A
ATP synthase, an enzyme which is embedded in the cellular membrane
ATP synthase phosphorylates ADP to form ATP as protons flow through it
4
Q
Define chemiosmosis
A
The synthesis of ATP though the movement of protons down their electrochemical gradient across a semi- permeable membrane, catalysed by ATP synthase
5
Q
How is the proton gradient maintained in chemiosmosis ?
A
Potential energy associated with excited electrons is coupled with the active transport of H+ ions across the membrane by the proton pumps
6
Q
A
