Attempt

1 of 3

Drag and drop the boxes into the correct order.

Rearrange the following steps involved in the ATP-PC energy system which generate ATP.

This is catalysed by the enzyme creatine kinase
Therefore, for each molecule of PCr, there is a net yield of 1 molecule of ATP
PCr is broken down into ADP + P + energy
The free energy released from the breakdown of PCr is used to rejoin ADP + Pi
This reaction is catalysed by the enzyme ATPase to produce ATP

This is your 1^st attempt! The marking algorithm gives more marks for getting the right order first time.
