ATP Flashcards
1
Q
What does ATP stand for?
A
Adenosine Tri Phosphate
2
Q
Whatis the structure of Adenosine Tri Phosphate
A
- always has the base ADENINE
- sugar ribose
- 3 phosphate heads
3
Q
Why does the cell require energy?
A
-synthesis - e.g. for large molecules like proteins
- transport - pumping molecules across the cell membrane
- movement - e.g. protein fibres cause muscle contraction
4
Q
What happens when ATP is broken down?
A
- Forms ADP and Pi
- by hydrolysis reaction
- releases energy
5
Q
Where is ATP made in the cell?
A
In the mitochondria
6
Q
Where does aerobic respiration produce ATP from?
A
glucose and oxygen
7
Q
How does the structure of ATP make it a good energy source? (1)
A
- small molecule - easy to move around within a cell
- water solution - reactions that require energy in cells occur in aqeuous solutions
8
Q
How does the structure of ATP make it a good energy source? (2)
A
- releases small amounts of energy - hydrolysis of a single ATP molecule releases a suitable amount of energy to dive on cellular respiration
9
Q
How does the structure of ATP make it a good energy source? (3)
A
Easily regenerated: when ATP is used, it is quickly regenerated by aerobic respiration in the cell
