D
Rough endoplasmic reticulum
Verified step by step guidance1
Identify the process in question: cellular respiration, which is the process cells use to convert biochemical energy from nutrients into ATP, the energy currency of the cell.
Recall that cellular respiration involves multiple stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation.
Understand that glycolysis occurs in the cytoplasm, but the majority of cellular respiration, especially the citric acid cycle and oxidative phosphorylation, takes place inside a specific organelle.
Recognize that the mitochondrion is the organelle responsible for the citric acid cycle and oxidative phosphorylation, making it the primary site of cellular respiration in eukaryotic cells.
Eliminate other options: chloroplasts are involved in photosynthesis, the Golgi apparatus modifies and packages proteins, and the rough endoplasmic reticulum synthesizes proteins, none of which are the main site of cellular respiration.
