Q

How many H bonds are there between base pairs in DNA?

A

A&T = 2 H Bonds
G&C = 3 H Bonds (makes this base pairing more stable that A&T)

16
Q

Why are the phosphate groups in adenosine triphosphate important?

A

When separated from ATP molecules, they phosphorylate other molecules in the cells, making them more reactive.

17
Q

Hydrolysis of ATP

A

catalysed by enzyme ATP hydrolase, ATP loses a phosphate group to form ADP (adenosine diphosphate) and an inorganic phosphate group (Pi)

18
Q

What enzyme catalyses the hydrolysis of ATP?

A

Enzyme ATP hydrolase.

19
Q

What goes the inorganic phosphate group do?

A

When separated from ATP molecules, they phosphorylate other molecules in the cells, making them more reactive.
