ATP

Question 1

What is ATP

Answer 1

single molecule of ATP is nucleotide derivative
-adenosine tri phosphate

Question 2

what is the function of ATP

Answer 2

immediate source of energy in biological processes

Question 3

what make up the ATP

Answer 3

-adenine- nitrogen containing base
-ribose- pentose sugar
-three inorganic phosphate group

Question 4

how is ATP hydrolased

Answer 4

-atp is hydrolased into ADP + Pi
-catalysed by the enzyme ATP hydrolase

Question 5

how is ATP resynthesised

Answer 5

during respiration ATP is resynthesised by the condensation of ADP + Pi which is catalysed by the enzyme ATP synthase

Question 6

describe how energy is released in the hydrolysis of ATP

Answer 6

-breaking one of the bonds between the inorganic phosphate group in a hydrolysis reaction releases small amounts of energy

Question 7

why is ATP an immediate source of energy

Answer 7

only one bond has to be hydrolysed to release energy

Question 8

describe the properties of ATP

Answer 8

1) releases small amounts of energy- less energy is wasted
2) small + soluble- easily transported around the cell
3) only one bond is hydrolysed to release energy- immediate source of energy
4)ATP cannot pass out of the cell- cell has an immediate supply of energy
