Which of the following parts of the cell provides most of its energy? Select one: a. cytoplasm b. mitochondria c. the nucleus d. Golgi bodies

The correct answer is b. mitochondria.<br /><br />Mitochondria are often referred to as the "powerhouses" of the cell because they are responsible for producing most of the cell's energy. They do this through a process called cellular respiration, where they convert nutrients into adenosine triphosphate (ATP), the primary energy currency of the cell. This process is essential for powering various cellular activities and maintaining the cell's overall function.
