Answer:
Lysosome............Digest macromolecules.
Step-by-step explanation:
Lysosomes is the membrane bound cell organelle that plays an important role in the cellular digestion. The proteins through the protein processing are transferred to the lysosomes as well.
Lysosomes are also known as suicidal bags as they have the ability to digest their own genetic material. The lysosomes contains acidic pH and different enzymes that are responsible for the degradation of macromolecules. Proteins, carbohydrates, lipids and nucleic acids are digested in the lysosomes.
Thus, the correct answer is option (a).
