Adenosine Triphosphate And Energy Transfer Flashcards
1
Q
What is adenosine triphosphate (ATP)?
A
A high energy immediate source of energy.
2
Q
What is adenosine diphosphate (ADP)?
A
Product formed with the removal of Pi from ATP.
3
Q
What is an enzyme?
A
A biological catalyst that speeds up reactions.
4
Q
What is ATPase?
A
The enzyme catalysing the breakdown of ATP.
5
Q
What is an exothermic reaction?
A
A chemical reaction causing the release of energy.
6
Q
What is an endothermic reaction?
A
A chemical reaction which absorbs energy.
7
Q
What is a coupled reaction?
A
Where the products of one reaction are used as the reaction are used as the reactants in another reaction.
8
Q
What 4 properties make ATP a good energy source?
A
- Small
- Soluble
- Easily broken down
- Easily transported around the cell.
9
Q
What is the ATP-PC system?
A
- ATP broken down by ATPase into ADP + Pi + energy
- PC broken down by creatine Kinase into Pi + C + energy.
- Energy + ADP + Pi combined to resynthesise ATP.
