Question

1) List the name and number of each molecule forming ATP.

2) List the name and number of each molecule forming ADP.

3) How do ADP and ATP differ in:

(a) Number of phosphate groups?
(b) Number of ribose molecules?
(c) Number of adenine molecules?
(d) amount of potential chemical energy.

4) Your muscles require energy to move your body. What chemical directly supplies your muscles with energy?

5) What process directly supplies your body with the energy it needs to change ADP back to ATP?

Thank you very, very, very much.

Answer 1

A adenosine

D di ('Di' means two)

P phosphate



A adenosine

T tri

P phosphate



Now look at a picture of ADP and ATP and count the number of ribose and adenine molecules in each.



The bond to the third phosphate molecule is described as a 'high energy bond' - you'll need to look up the figure the energy released at dephosphorylation.



Q.3. - what is ATP for?

Q.4. - what's the process that oxidises glucose molecules to release their energy (and produce carbon dioxide and water as by-products)?
