Hypothesis Experiment 1: Determining Baseline Metabolic Rates I hypothesize that the metabolic rate will be greater for the normal rate‚ then the thyroidectomized rat. The hypox rate will have the lowest metabolic rate. Experiment 2: Determining the Effect of Thyroxine on Metabolic Rate I hypothesize that metabolic rate will increase with the injection of thyroxine.

Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would.
