It regulates activities of the following organelles in the cell.
(1) Endoplasmic reticulum which synthesizes carbohydrates and lipids.
(2) Golgi apparatus which manufactures , stores and ships certain cellular products.
(3) Lysosomes which digest cellular macromolecules
(4) Mitochondria which provide energy for the cell.
