the relationship between ATP and ADP?

Question

what is the relationship between ADP and ATP?

Answer 1

when a cell makes energy, it forms these things.
The diagrams for these look like this:
ATP: A-P-P-P: because there are 3 phosphates
ADP: A-P-P: because there are 2 phosphates
AMP: A-P: because there is only one phosphate

ATP can be thought of as a 'fully charged' or 'new' battery, ADP is like a 'used' battery, and AMP is like a 'dead' battery.

i really hope this helps.

Answer 2

When ATP is broken to release energy for cells to use, the broken pieces are ADP and a phosphate.

ATP is adenosine triphosphate - three phosphates end-to-end. Breaking off one phosphate leaves only two phosphates stuck on the molecule, so it's ADP. The D stands for di- which means "two".

Later, the ADP can have a phosphate put back onto it to make ATP. Then it can be broken, put back together, broken, put back together, broken, ... almost indefinitely.
