Question
Match the component of eukaryotic cells (Column I) with its respective function(Column II).Column I Column IIP. Lysosome 1. Digestion of macromoleculesQ. Peroxisome 2. Detoxification of harmful compoundsR. Glyoxysome 3. Conversion of fatty acids to sugarS. Cytoskeleton 4. Involvement in cell motility(A) P-1, Q-2, R-3, S-4(B) P-2, Q-1, R-3, S-4(C) P-3, Q-1, R-2, S-4(D) P-4, Q-3, R-1, S-2
Solution
The correct answer is (A) P-1, Q-2, R-3, S-4.
Here's why:
P. Lysosome - 1. Digestion of macromolecules: Lysosomes contain digestive enzymes that break down waste materials and cellular debris in cells.
Q. Peroxisome - 2. Detoxification of harmful compounds: Peroxisomes are involved in the catabolism of very long chain fatty acids, branched chain fatty acids, D-amino acids, and polyamines, reduction of reactive oxygen species – specifically hydrogen peroxide – and biosynthesis of plasmalogens, i.e., ether phospholipids critical for the normal function of mammalian brains and lungs.
R. Glyoxysome - 3. Conversion of fatty acids to sugar: Glyoxysomes are specialized peroxisomes found in plants (particularly in the fat storage tissues of germinating seeds) and also in filamentous fungi. Their main function is to convert fatty acids into sugar for use by the organism.
S. Cytoskeleton - 4. Involvement in cell motility: The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including bacteria and archaea. It extends from the cell nucleus to the cell membrane and is involved in maintaining the shape of the cell, enabling cellular movement, cell division, etc.
