Question

Mitochondria perform all of the following functions except

• A. Nucleic acid synthesis
• B. $\beta$-oxidation of fatty acids
• C. ATP synthesis
• D. Polysaccharide degradation

Answer 1

The correct option is D Polysaccharide degradation

• Mitochondria synthesize ATP by the process of aerobic respiration during normal carbohydrate and $\beta$-oxidation of fatty acids.
• Carbohydrates and $\beta$-oxidation both require the Krebs cycle. As mitochondria have their own genetic material, nucleic acid synthesis also occurs inside mitochondria.
• The degradation of polysaccharides is not a function of mitochondria.
• However, mitochondria will be required to catabolize the monomeric products which will be obtained by breaking polysaccharides.

So, the correct answer is 'Polysaccharide degradation'
