Which specific organelle in eukaryotic cells is popularly referred to as the powerhouse of the cell due to its primary role in generating adenosine triphosphate via cellular respiration?

💡 Solution & Explanation

Mitochondria contain specialized inner membrane folds called cristae where oxidative phosphorylation and the Krebs cycle occur to synthesize cellular energy molecules in the form of ATP. Ribosomes are responsible for protein synthesis rather than cellular respiration. Golgi apparatus handles packaging and sorting of proteins and lipids. Endoplasmic reticulum provides intracellular transport networks and lipid biosynthesis platforms. Endosymbiotic theory explains the evolutionary origin of mitochondria from independent prokaryotic cells.
