Question

Choose the correct statement regarding Orthodox state of mitochondria

• A. It is an active state of mitochondria
• B. Matrix is enlarged while outer chamber is narrow
• C. Mitochondria are actively engaged in performing Krebs cycle, ETS, oxidative phosphorylation
• D. Cristae are more randomly distributed and outer chamber quite large

Answer 1

The correct option is B Matrix is enlarged while outer chamber is narrow

The Orthodox state is the most probable state of the mitochondrion in the cell. The morphological confirmation is even observed in isolated mitochondrion with low respiratory rates(less activity w.r.t. Kreb's cycle, ETS and Oxidative phosphorylation). The state is characterized by increased matrix volume (inner membrane content). So the matrix pushes the inner membrane in close proximity to the outer membrane making outer chamber narrow. In this confirmation the cristae shapes are like that of tubes, the short tubular cristae join to form the lamellar structure.

So, considering all the points we find that correct answer to the question is 'Matrix is enlarged while outer chamber is narrow'.
