Describe the fate of a single molecule of glucose as it goes through glycolysis and exits the Krebs cycle. Include the inputs to each reaction and all end products including all created energy storage molecules.

Expert Solution

A single glucose molecule is a six-carbon compound.
Through glycolysis, one glucose molecule is converted in to two pyruvate molecule (3-carbon compund).
Glycolysis takes place in cytoplasm and enzymes for further glucose catabolism is located in mitochondria.
Pyruvate can not enter in to mitochondria, therefore, it get converted to Acetyl Co-A (2-Carbon compound) with the help of pyruvate dehydrogenase enzyme and release one carbon as CO2.
Acetyl Co-A enters in to krebs cycle and releases two carbon of acetyl Co-A as two CO2.
Hence, For catabolism of one glucose molecule two rounds of krebs cycle is required.
