Sort the characteristics as belonging to the first half of the pathway that requires energy or to the second half of the pathway that produces energy during glycolysis.

The first half of glycolysis is energy investment phase while second half of glycolysis is energy generation phase.

Explanation:

There are two phases of glycolysis. The first half of glycolysis is energy investment phase while second half of glycolysis is energy generation phase. In the first half of glycolysis, two Adenine Tri Phosphate (ATP) are used or invested for the breakdown of glucose molecule into three carbon atom while in the second half of glycolysis, two NADH and four ATP molecules are formed.
