A student isolated several subcellular fractions from mammalian liver cells to study their biochemical properties. Which of the options correctly matches the eukaryotic organelle to its physiological role or biochemical feature?
Mitochondria — location of the chemical reactions of both glycolysis and the Krebs cycle.
Golgi apparatus — chemical modification of polypeptides, including the addition of carbohydrate chains to form glycoproteins.
Smooth endoplasmic reticulum — translation of mRNA molecules encoding lysosomal and secretory proteins.
Lysosomes — containment of hydrolytic enzymes that function optimally at the neutral pH of the cytosol.
