Role of Mitochondria in Cellular Respiration

In a typical eukaryotic cell, various organelles perform specific functions that are crucial for maintaining cellular health and operation. Among these organelles are the mitochondria, which are often referred to as the 'powerhouses of the cell.' They play a critical role in energy production through a process known as cellular respiration.

Cellular respiration involves several steps, one of which is the Krebs cycle. This cycle takes place in the mitochondrial matrix and is essential for the generation of ATP, which cells use as a primary energy currency. Understanding these organelles helps illustrate how cells convert nutrients into energy and maintain their metabolic functions.

Which of the following statements correctly describes the role of mitochondria in the cell?
