Inside cell, breakdown of pyruvate into carbon dioxide and water occurs in:
Cytoplasm
Ribosomes
Mitochondria
Nucleus
Breakdown of pyruvate into carbon dioxide and water requires oxygen and takes place in mitochondria.
Question 4 The breakdown of pyruvate to give carbon dioxide, water and energy take place in: (a) Cytoplasm (b) Mitochondria (c) Chloroplast (d) Nucleus
Question 12 The correct sequence of anaerobic reactions in yeast is (a) Glucosecytoplasm−−−−−−→Pyruvatemitochondria−−−−−−−−→Ethanol+Carbon dioxide (b) Glucosecytoplasm−−−−−−→Pyruvatecytoplasm−−−−−−→Lactic acid (c) Glucosecytoplasm−−−−−−→Pyruvatemitochondria−−−−−−−−→Lactic acid (d) Glucosecytoplasm−−−−−−→Pyruvatecytoplasm−−−−−−→Ethanol+Carbon dioxide
Statement 1: Glucose breaks down into a 3-carbon compound in the cytoplasm of the cell.
Statement 2: A pyruvate molecule breaks down into 3-molecules of carbon dioxide in mitochondria of the cell.
