Question

Oxysomes are present on

• A. Cell wall of algae
• B. Outer membrane of mitochondria
• C. Inner membrane of mitochondria
• D. None of the above

Answer 1

Answer: (C)

Inner membrane of mitochondria

Mitochondria are cell organelles of aerobic eukaryotes which take part in oxidative phosphorylation and Krebs' cycle of aerobic respiration. They are double membrane structure where the inner membrane is thrown in various types of fold called cristae. The cristae increase the surface area for absorption and also increases the efficiency of the mitochondria.

Oxysomes are F${}_1$ coupling factor present in the inner membrane, i.e. the cristae of mitochondria and are responsible for oxidative phosphorylation which involves the formation of ATP from ADP and inorganic phosphate.

So, the correct answer is option C.
