ATP Flashcards
How do you draw and label a molecule of ATP?
Diagram should include three phosphate groups (circles) joined to ribose (pentagon) and adenine (rectangle)
What are the components of a nucleotide?
Pentose sugar, phosphate plus organic base which contains nitrogen.
What are the components of ATP?
Ribose sugar, adenine and three phosphate groups joined together
Why is ATP formation endergonic?
Because energy is stored in the bond between the second and third phosphate.
Why is ATP hydrolysis exergonic?
Energy is released when the bond is broken between the second and third phosphate
Why is ATP known as the universal energy currency?
It is used by all living organisms to provide energy for nearly all reactions
Name three cellular processes that require ATP
Active transport, muscle contraction, protein synthesis, cell division, bulk transport.
How much energy is released when one mole of ATP is hydrolysed?
30.6kJ
