Learning Objective

I can describe how metabolic reactions help organisms use energy.

  • 1

    Metabolism is the term that describes how enzymes transform molecules through multi-step pathways to provide energy for the body.

  • 2

    Catabolic pathways break down larger molecules into smaller ones, releasing energy, while anabolic pathways assemble small molecules into larger ones, which requires energy.

  • 3

    ATP, or adenosine triphosphate, is a nucleotide with three phosphate groups that stores potential energy for cells to use in reactions.
