Question

When one glucose molecule undergoes one turn of aerobic respiration, 38 ATP molecules are produced. Cellular respiration takes partly in the cytoplasm and partly in mitochondria. During the process, some ATP molecules are produced in the cytoplasm, some in the mitochondrial matrix and some in the oxysomes on cristae. Maximum number of these ATP molecules is produced in

• A. Cytoplasm
• B. Mitochondrial matrix
• C. Cytoplasm and Mitochondrial matrix together
• D. Oxysomes on cristae

Answer 1

The correct option is D Oxysomes on cristae

The oxysomes or the F${}_1$ particles are present on the cristae in the inner membrane of the mitochondria. This is the site where the electron transport chain takes place. There are complexes which act as the electron carriers and the hydrogen ions are pumped in order to produce ATP. Maximum number of ATP are produced with the help of NADH and FADH${}_2$.

Thus, the correct answer is option D.
