Enzymes are produced in inactive form by the cell and enclosed in which of the following?
Correct answer: B. Lysosomes
- A. Mesosomes
- B. Lysosomes
- C. Peroxisomes
- D. All of these
Explanation
Lysosomes are membrane-bound organelles that contain digestive enzymes produced by the cell. These enzymes are initially produced in an inactive form to prevent them from digesting the cell itself. When activated, lysosomal enzymes help to break down and recycle cellular waste and foreign material and also play a role in processes such as apoptosis (programmed cell death) and autophagy (self-eating of cellular components).

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
