The respiratory chain a is activated by ADP b is inhibited b

The respiratory chain

a) is activated by ADP

b) is inhibited by ATP

c) is inhibited by the phosphate potential of the cell

d) all of the above

e) only a and c are correct

Solution

The respiratory chain

Only a and c are correct

ADP activates the respiratory chain in order to produce energy in form of ATP. ATP can be formed from ADP, ATP syntheses will cease to function because of the absence of its substrate ADP
