Final answer:
The statement that only lysosomal enzymes are sorted into vesicles destined for delivery to the lysosome is false. Other substances, not just lysosomal enzymes, are also targeted to the lysosome and other cellular destinations by vesicles, particularly as part of the broader endomembrane system's transport mechanisms.
Step-by-step explanation:
The statement that only lysosomal enzymes are sorted into vesicles destined for the lysosome is false.
While it is true that the primary function of the lysosome is to contain and transport digestive enzymes that break down cellular waste and foreign material, other proteins and molecules can also be sorted into vesicles that traffic to various parts of the cell, including the lysosome.
Transport vesicles move molecules between locations such as the rough endoplasmic reticulum and the Golgi apparatus. The Golgi apparatus plays a central role in sorting and directing vesicles to appropriate destinations, including the formation of lysosomes.
Lysosomal enzymes are important as they catalyze the hydrolysis of materials within the lysosome, allowing for the recycling of cellular components and destruction of pathogens. These enzymes maintain their activity at a much lower pH than enzymes in the cytoplasm.
However, it is the endomembrane system that facilitates the sorting and movement of various proteins, not just those for the lysosome.
Overall, while lysosomal enzymes are certainly routed to the lysosome, they are not the only proteins that follow this pathway, indicating that the original statement is too restrictive and therefore false.
