D
Lysosome
Verified step by step guidance1
Understand the process of cellular respiration, which is the metabolic pathway that converts biochemical energy from nutrients into adenosine triphosphate (ATP), the energy currency of the cell.
Recall that in eukaryotic cells, cellular respiration primarily occurs in a specific organelle that has a double membrane and its own DNA, allowing it to produce ATP efficiently.
Identify the organelle responsible for this function by comparing the roles of the options: Golgi apparatus (involved in protein modification and sorting), Rough endoplasmic reticulum (involved in protein synthesis), Lysosome (involved in digestion and waste removal), and Mitochondrion.
Recognize that the mitochondrion is known as the 'powerhouse of the cell' because it is the site where the Krebs cycle and oxidative phosphorylation take place, leading to ATP production.
Conclude that the mitochondrion is the primary site of cellular respiration and ATP production in eukaryotic cells.
