3.11 ATP

Question 1

what are the uses for ATP?

Answer 1

Biosynthesis of macromolecules
Active transport
Nerve transmisson
Growth and repair
Movement
Emission of light

Question 2

state the advantages of ATP

Answer 2

-releases energy in small amounts (one phosphate group at a time) to reduce the waste of energy
-small and soluble makes it easy to transport
-cant leave the cell so the cell will always have an energy supply
-easily regenerated

Question 3

what is ATP?

Answer 3

A phosphorylated nucleotide made up of 3 phosphate groups, a pentose sugar-ribose and a nitrogenous base- adenine.

Question 4

how is energy released from ATP?

Answer 4

the phosphate groups are covalently bonded together and store potential energy so when these bonds are broken they release this energy. (approximately 30.6KJmol-1 per bond)

Question 5

what is the reversible equation for the breaking down of ATP?

Answer 5

energy + ADP +Pi <=> ATP +H2O

Question 6

what enzymes are involved in the condensation and hydrolysis reaction of ATP

Answer 6

condensation= ATP synthase
hydrolysis= ATPase
