What is the function of mitochondria?
  • Mitochondrial ATP Generation: Mitochondria serve as the primary energetic organelles ("powerhouses") of eukaryotic cells, coupling the citric acid cycle (TCA cycle) and electron transport chain with chemiosmotic ATP synthesis via ATP synthase.
  • Comparative Cellular Roles: Nucleotide synthesis takes place primarily in the cytosol; fatty acid synthesis occurs in the cytosol (and chloroplasts in plants); amino acid transamination and degradation occur across both cytosol and mitochondrial compartments.

Correct option: (1) Generation of ATP
