Which of the Following Glycolytic Reactions is Freely Reversible

Question

Which of the following glycolytic reactions is freely reversible?
A)hexokinase
B)phosphofructokinase
C)triose phosphate isomerase
D)pyruvate kinase
E)none of the above

Accepted Answer

Triose phosphate isomerase catalyzes the reversible interconversion of dihydroxyacetone phosphate and glyceraldehyde-3-phosphate, making it freely reversible. Hexokinase, phosphofructokinase, and pyruvate kinase are irreversible enzymes in glycolysis.
