In eukaryotic cells, the oxidation of pyruvate occurs in:

Question

Quizplus · Accepted Answer

The oxidation of pyruvate occurs in the matrix of the mitochondria in eukaryotic cells. This process is part of cellular respiration and produces ATP molecules for energy. The cytoplasm is where the initial stage of cellular respiration, glycolysis, occurs, but the full oxidation of pyruvate occurs in the mitochondria. The nucleus contains genetic material and is not involved in cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism, but not pyruvate oxidation. Vacuoles are involved in storage and transport of various substances within the cell, but not in cellular respiration.
