In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver. In the liver, lactate is converted back into glucose by gluconeogenesis. For each given enzyme, identify whether it is involved in the glycolysis pathyway, gluconeogenesis pathway, both pathways, or neither pathway. The enzyme triose phosphate isomerase is involved in

The correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.

Explanation:

The enzyme triose phosphate isomerase includes the Glyceraldehyde 3 P dehydrogenase. It is one of the enzymes used in glycolysis as well as gluconeogenesis. These enzymes catalyze the conversion of glyceraldehyde to 1,3 bis phosphoglycerate.

Thus, the correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.
