Glycolysis is an example of

Question

A. A decomposition reaction
B. A pyrolysis reaction
C. A synthesis reaction
D. A double displacement reaction

Answer 1

Glycolysis is the breakdown of glucose to form pyruvate.  So, it is essentially a decomposition reaction, according to chemical definitions.  But since it also results in synthesis of pyruvate, it might be considered a synthesis, but that would be a stretch because of the intervening steps.  In general, in chemistry, synthesis is considered to be of the form A + B => C.

Decomposition is considered to be A => B+ C.  So, glycolysis meets the definition of decomposition better than synthesis.  It is clearly NOT pyrolysis nor double displacement.
