What is NOT a function of the cytoplasm?

The cytoplasm plays a crucial role in cellular function, but it is not directly responsible for energy production within the cell. In eukaryotic cells, energy production primarily occurs in specialized organelles like mitochondria, where cellular respiration takes place to convert nutrients into energy for the cell.

While the cytoplasm does facilitate various processes that contribute to the overall metabolic activities of the cell, its main functions include filling the cell to maintain its shape, housing organelles, and assisting in the transport of materials within the cell. The substances dissolved in the cytoplasm and the organelles suspended within it are essential for those processes, but the act of generating energy is specifically tied to the mitochondria and certain other organelles, depending on the type of cell. Thus, energy production is not a function attributed specifically to the cytoplasm.
