ATP:

Question 1

Why is ATP needed?

Answer 1

= cells need a way to transfer energy from a glucose molecule into smaller useful amounts

Question 2

What is the structure of ATP?

Answer 2

= 3 phosphate heads
= ribose sugar
= adenine
= ADENOSINE
= takes a small amount of energy to break the covalent bond holding the last phosphate head in place

Question 3

What happens when this bond is broken?

Answer 3

= a great deal of energy is released
= used by processes in cell

Question 4

What is the ATP hydrolosis?

Answer 4

ATP + water=
= catalysed by the enzyme ATPase
= forms ADP, phosphate group,

Question 5

What kind of energy source is ATP?

Answer 5

= immediate energy source
= from the site of respiration to the parts of the cell that require energy

Question 6

What happens to ADP + phosphate head?

Answer 6

= recylcled back to ATP
= respiration in animal cells and respiration and photosynthesis in plant cells

Question 7

What is it a phosphorylation reaction?

Answer 7

= adding phosphate back into ADP
= catalysed by the ezzyme ATP synthase
= condensation reaction
