• Unit 5: Enzymes, Metabolism, Cellular Respiration

    The cell uses enzymes and metabolic pathways to conduct the chemical reactions within the body. The sum total of every chemical reaction in your body is known as your metabolism. Understanding the reactions that comprise your metabolism is essential to understanding how your body acquires and uses energy to survive.
