Q

how much energy is needed to synthesis one mole of ATP?

A

30.6 KJ

16
Q

what is the addition of a phosphate to ADP called?

A

phosphorylation

17
Q

why is ATP the perfect energy currency for the cell compared to glucose?

A

only require one enzyme
involves one single step that immediately releases energy
ATP releases energy in small amounts when and where it is needed

18
Q

why is glucose energy not as efficient as ATP energy?

A

many enzymes are needed
involves many steps and takes longer to release energy
glucose releases energy in large amounts all at once

19
Q

what cellular activities does ATP provide energy for?

A

active transport
metabolic processes
movement
nerve transmission
secretion
