What does ATP stand for?
Adenosine triphosphate
1 of 15
Why is ATP needed?
A cell can't get its energy directly from glucose, so the energy released from glucose is used to make ATP
2 of 15
What three parts make up an ATP molecule?
Adenine, Ribose and Phosphate groups (3)
3 of 15
Draw a diagram of ATP
Page 22 of revision guide
4 of 15
Why is ATP a nucleotide derivative?
It is a modified version of a nucleotide
5 of 15
How does ATP reach parts of the cell that needs energy?
It diffuses
6 of 15
Where is the energy in ATP stored?
In high energy onds between the phosphate groups
7 of 15
What reaction occurs to break down ATP and release energy?
A hydrolysis reaction
8 of 15
What enzyme catalyses the hydrolysis reaction?
ATP Hydrolase
9 of 15
How is ATP hydrolase adapted to its function?
It can be 'coupled' to other energy-requiring reactions i the cell- the energy released can be used directly to make the couple reaction happen rather than the energy being transferred as heat
10 of 15
the released phosphate is inorganic- what does this mean?
It doesn't contain any caron atoms
11 of 15
What is phosphorylation?
When an inorganic phosphate is added to another compound which often makes the compound more reative
12 of 15
Once ATP is broken down, how can it be synthesised agan?
ATP is synthesised by a condensation reaction between ADP and Pi
13 of 15
Which enzyme catalyses this condensation reaction?
ATP Synthase
14 of 15
Draw a diagram showing how ATP is made and broken down
