Final answer:

Proteins destined for the peroxisomal matrix do not pass through the TOM complex, as it is specific to mitochondrial protein import, making the statement false.

Step-by-step explanation:

The statement that proteins destined for the peroxisomal matrix must pass through the TOM complex is false. The TOM complex, or translocase of the outer membrane, is specifically involved in the recognition and translocation of proteins into the mitochondria. Peroxisomes, on the other hand, have a different protein import machinery that recognizes peroxisomal targeting signals (PTS). Proteins with such signals are directly imported into the peroxisome from the cytosol. In fact, mitochondrial and peroxisomal import pathways are distinct, and the TOM complex plays no role in peroxisomal protein import.
