In which organelle proteins, fats and carbohydrates synthesized in the cell accumulate?

The accumulation of organic substances such as proteins, fats and carbohydrates occurs in the Golgi apparatus. It is a membrane structure that is characteristic of eukaryotic cells. This structure is mainly found in the central part of the cell. It resembles a system of tubes that are located one above one. All substances that are synthesized in the endoplasmic reticulum are excreted using the Golgi complex. But not all eukaryotic cells have this structure. For example, they are absent in the conducting cells of plants, erythrocytes of mammals, and so on.
