Overall, catabolic reactions overall, catabolic reactions take in energy occur outside the cell membrane release energy occur mainly in the liver take place in the nucleus of the cell

Overall, catabolic reactions release energy.

Explanation:

Catabolic reactions (also called “catabolism”) break down larger, more complex molecules into smaller molecules and release energy in the process.  Some of the energy is released as heat and increases the temperature of the cell. Sometimes the energy is stored in the chemical bonds of another molecule.
