Question

How does ADP differ from ATP? ATP has one more phosphate group than ADP. ADP has one more adenine group than ATP. ATP has one more adenine group than ADP. ADP has one more phosphate group than ATP.

Answer 1

The correct answer is A. ATP has one more phosphate group than ADP

ATP stands for Adenosine Triphosphate the prefix "Tri" means 3. So this means that ATP has one more phosphate group than ADP.

ADP stands for Adenosine diphospate the prefix "Di" means 2. So the correct answer is  A. because ADP has less phosphate groups than ATP

Hope this helps

Answer 2

If you know their full forms, It'll be easy to choose the answer,

ATP stands for Adenine *Tri*phosphate

and

ADP stands for Adenine *di*phosphate.


*Tri* comes after *Di* as prefix before the compound.

Therefore it implies that,

*ATP has one more phosphate group than ADP.*
