What do lysosomes contain that aids in cellular digestion?

Lysosomes are membrane-bound organelles filled with enzymes that play a critical role in digesting various cellular substances. These enzymes, such as proteases, lipases, and glycosidases, break down macromolecules like proteins, lipids, and carbohydrates into their smaller building blocks. This function is essential for recycling cellular components, processing nutrients, and eliminating waste products, thereby maintaining cellular homeostasis.

The presence of these digestive enzymes within lysosomes distinguishes them as the primary centers for intracellular digestion. Without these enzymes, the cell would be unable to effectively break down and recycle materials, leading to the accumulation of cellular debris and potentially harmful substances. The other options, while related to cellular function, do not pertain to the primary role of lysosomes in digestion.
