Figure 1. Anabolic pathways are those that require energy to synthesize larger molecules. ... Both types of pathways are required for maintaining the cell's energy balance. It is important to know that the chemical reactions of metabolic pathways don't take place spontaneously.

Are anabolic reactions spontaneous?

Anabolic reactions require energy in order to make the smaller compounds into larger ones, so they are not spontaneous.

Do anabolic pathways depend on pathways?

Anabolic pathways are those that require energy to synthesize larger molecules. Catabolic pathways are those that generate energy by breaking down larger molecules. Both types of pathways are required for maintaining the cell's energy balance.
