ATP 2

Question 1

What does ATP become when it loses a phophate

Answer 1

Adenosine di phosphate (ADP)

Question 2

Why does ATP hydrolyse in the first place

Answer 2

To gain energy,them a process such as cellular respiration can provide the energy needed to add a phosphate to ADP to make it ATP

Question 3

When ATP is hydrolysed what does it involve an addition of

Answer 3

Water

Question 4

What bond contributes to the unstable nature of ATP

Answer 4

Bond between 2nd and 3rd phosphate as the phosphates with their negative charges don’t like being arranged like this

Question 5

What type of reaction is the change from ATP to ADP

Answer 5

An exorgonic reaction

Question 6

What is an exorgonic reaction

Answer 6

A reaction when endorgonic processes are necessary e.g. cell transport moving molecules against the gradient and does this using ATP without this ATP would be useless.

Question 7

What is it called when the phosphate lost in ATP enter s a molecule in an endorgonic process

Answer 7

We say the molecule has been phosphorylated
