Biological Molecules- ATP

Question 1

What is ATP?

Answer 1

Adenosine Triphosphate (Energy Carrier Molecule – delivers energy for life
processes)

Question 2

Structure of ATP?

Answer 2

 made from 1 adenosine and 3 phosphates
 formation: ADP + Pi (+ energy used) = ATP
 condensation reaction using ATP Synthase
 carries energy in its bonds
 breakdown: ATP = ADP + Pi (+ energy released)
 hydrolysis reaction using ATP Hydrolase
 releases energy from its bonds

Question 3

Uses of ATP (releases energy) in organisms?

Answer 3

protein synthesis
 organelle synthesis
 DNA replication
 cell division (mitosis)
 active transport
 metabolic reactions
 movement
 maintaining body temperature
