The energy required for active transport is often provided by the hydrolysis of ATP. In plants we can study the dependence of the membrane potential on ATP by observing the effect of cyanide (CN–), What wil be the effect of cyanide(Cn-),

a.) Cyanide rapidly poisons the mitochondria as ATP synthesis is inhibited, the membrane potential falls below -50mV

b.) Cyanide inhibits the electron transport but not inhibit the ATP synthesis, the membrane potential positive

 c.) Cyanide inhibits the electrogenic ion transport the pH of the external medium increases while the cytosol becomes acidic because H+ remains inside the cell

 d.) Cyanide inhibits the electrogenic ion transport the pH of the external medium acidic while the cytosol becomes alkaline because H+ remains outside of the cell
