What does ATP stand for?
Adenosine triphosphate
What do cells use ATP for?
The immediate energy source for biological processes
What is ATP formed from?
A molecule of ribose, a molecule of adenine and three phosphate groups
How does ATP release energy?
Through hydrolysis
What is the enzyme that catalyses the hydrolysis of ATP?
ATP hydrolase
What can the energy released during hydrolysis be coupled with?
Energy-requiring reactions within cells
What can the inorganic phosphate released in hydrolysis be used for?
To phosphorylate other compounds to make them more reactive
What is ATP resynthesised in?
The condensation of ADP and Pi (inorganic phosphate)
What is this reaction catalysed by?
ATP synthase
