Primary active transport of a solute across a membrane driven by decarboxylation of a cytoplasmic substrate. Primary active transport is catalysis of the transport of a solute across a membrane, up the solute's concentration gradient, by binding the solute and undergoing a series of conformational changes. Transport works equally well in either direction and is driven by a primary energy source.
