3.1 ATP Flashcards
(45 cards)
What is ATP?
Nucleotide
What enzyme hydrolyses the terminal bond?
ATPase
Which bond is bond is hydrolysed?
Terminal
How is ATP reformed?
Phosphorylation
ATP=
ADP + Pi
What reaction makes ATP?
Condensation
What is ATP made of?
3 Phosphate groups, ribose sugar and an organic base (Adenosine)
Where ATP synthesis takes place?
Internal membrane of mitochondria
What protons must pass through
ATP synthetase
Where ATP synthetase is found?
Within stalked particles
What the flow of protons generates?
Electrochemical gradient
What electrochemical gradient drives?
Phosphorylation of ADP
Process of ATP synthesis is called?
Chemiosmosis
Chemiosmosis
Flow of protons down an electrochemical gradient, through ATP synthetase which provides the potential energy necessary to synthesise ATP by phosphorylation
Where do protons flow in Mitochondria
From Inter membrane space into matrix
Where do protons flow in Chloroplasts
Across the thylakoid space into the stroma
Parts of the chloroplast
Thylakoid space
Stalked particles containing ATP synthetase
Outer membrane ]thylakoid membrane
Stroma
Parts of mitochondria
Inter membrane space
Matrix
Crista
Outer membrane
Stalked particles containing ATP synthetase
Where in chloroplasts are (Protons are pumped across a membrane by proton pumps fuelled by electron energy)
Thylakoid Membrane
Where in chloroplasts (A high concentration of protons (hydrogen ions) build up)
Thylakoid space
Where in chloroplasts (Protons flow down a concentration gradient to provide energy for ATP synthesis)
stalked particles contains ATP synthetase
Where in chloroplasts (Free electrons are taken up by a final electron acceptor)
Stroma
Where in mitochondria (Protons are pumped across a membrane by proton pumps fuelled by electron energy)
Crista
Where in mitochondria (A high concentration of protons (hydrogen ions) build up)
Intermembrane space
