Bio molecules ATP

Question 1

Where is energy obtained from

Answer 1

Glucose via respiration
~ then stored as ATP

Question 2

What is the structure of ATP?

Answer 2

Nucleotide derivative
Composed of:
~1x adenine
~1x ribose sugar
~3x phosphate group

Question 3

Where is atp made?

Answer 3

Mitochondria
~site of cellular respiration

Question 4

Where is energy in ATP stored?

Answer 4

Phospho-hydride bonds between phosphate groups
~ to release energy bonds must be broken

Question 5

What happens during the hydrolysis of ATP?

Answer 5

High energy phospho-hydride bonds broken and energy released.
Forms ADP and Pi

Question 6

What happens during ATP synthesis?

Answer 6

ADP + Pi —> ATP
Involves condensation reaction
ATP synthase catalyses reaction
Respiration - synthesised in mitochondria + during glycolysis (in cytoplasm)

Question 7

What happens during phosphorylation?

Answer 7

Phosphate group added to another molecule
~ make it more reactive
~carried out by kinases
(enzymes)
Releases Pi from hydrolysis can be used for this.
