1
Q
What is entropy?
A
The degree of randomness or disorder from a system
2
Q
What is a catabolic reaction?
A
An energetically favourable reaction - energy is released
3
Q
What is the difference in order and disorder?
A
Non-living things left to themselves eventually become disordered

5
Q
What is a coupled reaction?
A
Two reactions that occur together, one reaction is necessary for the other to occur
6
Q
What is ATP?
A
A molecule which contains three phosphates held together by high energy bonds
7
Q
