Mitochondria are cell organelles of aerobic eukaryotes. These are site of aerobic respiration, where Krebs cycle occurs in matrix, while ETS and oxidative phosphorylation enzymes are located in inner membrane. They are called powerhouses of cell because they produce energy in the form of ATP. They are the major centres of release of energy in the aerobic respiration.

Direction: In the following questions, a statement of assertion (A) i...
Assertion: Mitochondria are called 'powerhouses' of the cell.
Reason: Mitochondria produce cellular energy in the form of ATP.
The correct answer is option 'A': Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
Explanation:
- The mitochondria are known as the 'powerhouses' of the cell because they are responsible for producing energy in the form of ATP (Adenosine Triphosphate), which is the energy currency of the cell.
- The mitochondria carry out a process called cellular respiration, where they convert glucose and oxygen into ATP through a series of biochemical reactions.
- The reason provided correctly explains why mitochondria are referred to as 'powerhouses' of the cell because they produce the energy required for various cellular activities.
- Without mitochondria, cells would not have sufficient energy to carry out their functions, and the cell's overall metabolism would be severely impacted.
- Mitochondria are present in most eukaryotic cells, including plant and animal cells. They have an inner and outer membrane, with the inner membrane containing specialized structures called cristae, where the majority of ATP production occurs.
- The structure and function of mitochondria make them essential organelles for cellular energy production and overall cell survival.
- Therefore, the reason provided for the assertion is correct, and it explains why mitochondria are called 'powerhouses' of the cell.
In conclusion, the assertion that mitochondria are called 'powerhouses' of the cell is true, and the reason provided, which states that mitochondria produce cellular energy in the form of ATP, is the correct explanation for this assertion.
