Coupled pores Two molecules transported together Symport: Both molecules move in the same direction Phosphorylation Change of configuration ATP + H 2 O ADP + Pi Dephosophorylation P P P
Antiport pores Molecules move in opposite directions (one in the other out) e.g. Na + (out) and K + (in) ATPase is an antiport pore protein ATP is made on the mitochondria inner membranes by throwing an ATPase into reverse
