Understand that ATP (adenosine triphosphate) is the main energy currency of the cell, used to power various cellular processes.
Recall the functions of the listed organelles: the rough endoplasmic reticulum is involved in protein synthesis, the Golgi apparatus modifies and packages proteins, and lysosomes digest cellular waste.
Identify the organelle known as the 'powerhouse of the cell,' which generates ATP through cellular respiration.
Recognize that the mitochondrion carries out oxidative phosphorylation, a process that produces most of the cell's ATP.
Conclude that the mitochondrion is primarily responsible for producing ATP, making it the correct answer.
