Four of these committees (for prizes in physics, chemistry, physiology or medicine, and literature) are working bodies within their prize awarding. These four Nobel Committees only propose possible candidates, while the final decision is taken in a larger assembly. This assembly is made up of the entire academies for the prizes in physics, chemistry, and literature, as well as the 50 members of the Nobel Assembly at the Karolinska Institute for the prize in physiology or medicine.
