Which organelle is universally known as the powerhouse of the cell due to its role in cellular respiration and ATP generation?

💡 Solution & Explanation

Mitochondria generate most of the chemical energy needed by cellular biochemical reactions through adenosine triphosphate synthesis during aerobic respiration. Ribosomes assemble proteins, Golgi apparatus modify and package macromolecules, and lysosomes contain digestive enzymes for waste breakdown. Mitochondrial inner membranes feature folds called cristae that maximize surface area.
