• A. Mitochondrion is a cell organelle that possesses a double membrane
• B. Mitochondria contain ATP
• C. The enzymes of the Krebs cycle and the cytochromes are found in mitochondria
• D. Mitochondria are found in almost all kinds of cells

Answer 1

The correct option is C The enzymes of the Krebs cycle and the cytochromes are found in mitochondria

Mitochondria are the tiny cell organelles present in the cytoplasm which are involved in the release of energy from food, thus they are called as the powerhouse of the cell. Here cellular respiration occurs which requires the enzymes and cytochromes of aerobic respiration.

So, the correct statement is ' The enzymes of the Krebs cycle and the cytochromes are found in mitochondria'.
