Which organelle is primarily responsible for energy production in many cells?

Energy production in cells happens when nutrients are converted into ATP through cellular respiration inside mitochondria. These organelles house the enzymes of the Krebs cycle and oxidative phosphorylation, and their inner membrane folds (cristae) increase the surface area for energy-generating reactions. Ribosomes are for making proteins; the nucleolus handles ribosomal RNA synthesis and ribosome assembly; vacuoles store substances and help regulate turgor. Because mitochondria generate most of the cell’s ATP, they are the primary organelle responsible for energy production in many cells.
