Cell Bio - ATP release, role and regen Flashcards
How do cells get energy?
By releasing the chemical energy stored in food
What is the role of ATP?
ATP is responsible for providing the energy required for cellular activites.
What is ATP made up of?
1 adenosine molecule and 3 phosphate groups (Pi)
How can the energy stored in ATP be released?
By breaking down ATP into adenosine diphosphate (ADP) and a phosphate group.
How can ATP be regenerated?
ATP is regenerated by joining a molecule of ADP to a phosphate group using energy
List 5 examples of cellular activities that require energy
- cell division
- protein synthesis
- active transport
- muscle cell contraction (in animal bodies)
- transmission of nerve impulses (in animal bodies)
What is the word equation for the breakdown of ATP in cells?
ATP → ADP + Pi + Energy
What is the word equation for the formation of ATP in cells?
ADP + Pi + Energy → ATP
