Question

1. the following reaction in gluconeogenesis circumvents the reaction catalyzed by pyruvate kinase in glycolysis.

pyruvate carboxylation
oxaloacetate transport into the cytosol
pyruvate decarboxylation
glucose - 6 - phosphate dephosphorylation

Explanation:

In gluconeogenesis, pyruvate carboxylation circumvents the pyruvate - kinase - catalyzed step in glycolysis. Pyruvate is carboxylated to oxaloacetate by pyruvate carboxylase, which is a key step to bypass the irreversible pyruvate kinase step in glycolysis.

Answer:

Pyruvate Carboxylation
