Free Respоnse #3 (25pts): Physiоlоgy of the weight reduced stаte аnd muscle contrаction efficiency. Part 1 (6pts): Describe the mechanism by which the brain senses a reduction in the body’s long term energy reserves. Your answer should reference a specific hormone, the cell-type from which the hormone is released and the effect of weight loss on the hormone signaling pathway. Part 2 (9pts): Give three examples of physiological changes that occur during the PWRS and describe how each promotes weight regain. Part 3 (10pts): Explain the molecular basis for the enhanced efficiency of muscle contraction in the weight reduced state. Your answer must define “metabolic shift” and compare fast- versus slow-twitch muscle fibers in terms of their metabolic shifts. You must then describe how weight loss influences metabolic shift in muscle in terms of two key molecular markers.
