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.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
