[OLD] Biological Molecules - ATP Flashcards
What does ATP stand for?
Adenosine TriPhosphate
What does ATP consist of?
Adenine (nitrogenous base)
Ribose (5 carbon sugar (pentose)
3 phosphate groups (PO4-)
How does ATP become ADP?
ATP loses a phosphate group by hydrolysis
What does ADP stand for?
Adenosine DiPhosphate
What happens when ATP loses a phosphate group to become ADP?
Energy is released as the bond is broken
What happens to the energy released when ATP becomes ADP?
It can be used by the cell for other purposes e.g active transport, moving vesicles, making cilia waft/beat, constructing large polymer molecules etc
How can ATP be regenerated from ADP?
By adding a phosphate molecule back onto it
What do you need to regenerate ATP from ADP?
The chemical energy provided by the food you eat
Give 3 ways in which the properties of ATP make it a suitable supply of energy in biological processes
It releases energy is small, manageable amounts appropriate for the uses of the cell.
It is made quickly and easily through a one step reaction.
It is soluble so can move around inside a cell easily without leaving the cell.
What’s a simple equation to show how ATP is synthesised from ADP
ADP + phosphate group -> ATP
