3.1.6 ATP Flashcards
1
Q
What is ATP made of ?
A
ATP is made from the nucleotide base adenine combined with a ribose sugar and
three phosphate groups
2
Q
When energy is needed by a cell what happens ?
A
ATP —–>ADP
Hydrolysis - phosphate bond broken energy released
ATP hydrolase
3
Q
What is phosphorylation ?
A
Released organic phosphate can be added to another compound (this is called
phosphorylation) which often makes the compound more reactive
4
Q
How is ATP resynthesised ?
A
ATP can then be re-synthesised in a condensation reaction between ADP and P.
The enzyme ATP synthase catalyses it during both respiration and
photosynthesis.
