1.5 ATP

Question 1

What is the structure of ATP?

Answer 1

The components of ATP are:
- Adenine - a nitrogenous base.
- Ribose - a five-carbon sugar.
- Three phosphate groups

Question 2

What is the function of ATP

Answer 2

ATP is used to power most energy-requiring cellular reactions.

Question 3

What is the equation for the hydrolysis of ATP?

Answer 3

ATP + H2O → ADP + Pi (+ energy)

Question 4

Which enzyme aids the hydrolysis of ATP?

Answer 4

ATP hydrolase

Question 5

How is energy released from the hydrolysis of ATP?

Answer 5

Energy is released during the hydrolysis of ATP as one of the phosphate bonds is broken.

Question 6

What is the inorganic phosphate from the hydrolysis of ATP used for?

Answer 6

The inorganic phosphate released in ATP hydrolysis can be used to phosphorylate other compounds.
This often makes the compounds more reactive.

Question 7

What is the equation for the resynthesis of ATP?

Answer 7

ADP + Pi (+ energy) → ATP + H2O

Question 8

Which enzyme catalyses ATP resynthesis?

Answer 8

ATP synthase
