Final answer:
The energy for the transportation of large molecules to the nucleus comes from ATP hydrolysis.
Step-by-step explanation:
The energy for the transportation of large molecules to the nucleus comes from ATP hydrolysis as the nuclear proteins enter the nucleus. ATP (adenosine triphosphate) is a molecule that stores and releases energy for cellular processes, including active transport. When ATP is hydrolyzed, it releases a phosphate group, which provides the energy needed for the transportation of molecules across the nuclear membrane.
