Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use

Answer 1

The organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use is the mitochondrion (plural: mitochondria). Mitochondria are often referred to as the "powerhouses" of the cell because they produce adenosine triphosphate (ATP), the main energy currency of the cell, through a process called cellular respiration.
