ATP-ADP Cycle

In which structure, ATP or ADP, is more energy stored? Where is the energy stored?

ATP has more energy stored and it is stored in the 2nd and 3rd phosphate bonds

What does ATP stand for?

Adenosine triphosphate

Which molecules are contained in both ATP and ADP?

Adenosine, phosphate, ribose

Exergonic

Chemical reactions that release energy ATP --> ADP + P + energy

Endergonic

A chemical reaction that requires the input of energy in order to proceed. ADP + P +energy --> ATP

What is the structural difference between ATP and ADP?

ADP has two phosphates while ATP has three.

Describe what takes place in the process of converting ADP to ATP.

Another phosphate group is added to ADP and results in ATP and water.

ATP - ADP cycle.

How a cell regenerates its ATP supply. ADP forms when ATP loses a phosphate group, then ATP forms as ADP gains a phosphate group.

Describe what happens in the process of converting ATP to ADP.

Hydrolysis breaks the bond of the 3rd phosphate from the ATP producing ADP and releasing energy

Why do cells need energy released from the breakdown of ATP?

Movement, maintenance of body temperature, active transport,chemical reactions, protein synthesis, DNA replication,

What are the components of ATP?

adenine, ribose, 3 phosphate groups

what is AMP

adenosine monophosphate. - not 1, but 2 phosphate groups are removed from the ATP Molecule
