Question

Quizplus · Accepted Answer

A secondary lysosome is formed when a primary lysosome fuses with a vesicle containing material to be degraded. The enzymes in the primary lysosome are then able to break down the material through hydrolysis, making it a secondary lysosome. Therefore, choice C is the correct answer. Choices A, B, D, and E are incorrect as they do not accurately describe the function or characteristics of a secondary lysosome.
