The export of protein M by these cells would involve A - VCE - SSCE Biology - Question 7 - 2013 - Paper 1

The export of proteins from cells primarily involves the Golgi apparatus, an essential organelle responsible for processing and packaging proteins for secretion. Once proteins are synthesized in the endoplasmic reticulum (ER), they are transported to the Golgi apparatus, where they undergo further modifications and are sorted for delivery to their final destinations, either inside or outside the cell.

In contrast, the other options listed do not play a direct role in the export process:

• A. Centrioles: These structures are involved in cell division and the organization of microtubules but do not facilitate protein export.
• B. Lysosomes: These organelles are responsible for digestion and waste processing within the cell but do not export proteins.
• D. Chromosomes: These structures contain genetic material and are involved in cell division and heredity, but they do not participate in the export of proteins.

Thus, the correct answer is C, the Golgi apparatus.
