Anabolic pathways are most active with resources from the environment are available and the energy charge is high, which leads to activation of pathways that synthesize macromolecule to store as fuel.

Catabolic pathway are active when resources from the environment are not available and energy charge is low, which leads to activation of pathways that break down stored fuels to generate needed ATP.

Anabolic pathways are most active when the energy charge is vhereas catabolic pathways are most active when the energy charge is $$ The source of energy for $$ pathways is stored fuels whereas the source of energy for

$$ Jathways is abundant resources from the environment $($nutrients or sunlight$).$
