Events associated with lysosomal disorders are mentioned below. Arrange them in a sequence with respect to their occurrence:i. Mutationii. Storage diseasesiii. Accumulation of substances within the cellsiv. Deficiency of lysosomal enzymesv. Metabolic sluggishness
Correct answer: B. i, iv, v, iii, ii
- A. i, ii, iii, iv, v
- B. i, iv, v, iii, ii
- C. v, iv, iii, ii, i
- D. ii, iii, iv, v, i
Explanation
Mutations (i) in the genes responsible for lysosomal enzymes result in their deficiency (iv). This deficiency leads to metabolic sluggishness (v), as the substances that need to be broken down are not processed efficiently. Consequently, these substances accumulate within the cells (iii), culminating in storage diseases (ii). The incorrect options either misplace the events or start with outcomes rather than causes.

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.
