We investigate the shape transformation of a vesicle incorporated with a long and flexible polymer. We evaluate the grand canonical partition function of the polymer to consider the effects of chain conformational changes on the membrane. It is found that the polymer loops with the ends adsorbed or anchored on the membrane play a major role on vesicular budding transition.
