UCT causes the endotherm’s metabolic rate to increase. We can hypothesize that when the temperature falls below the LCT or above the UCT‚ the percent O2 consumption will increase‚ and thus‚ the metabolic rate. The hypothesis was supported by the result received in this lab. The thermal neutral zone (TNZ) of an endotherm is its temperature tolerance range. For the mouse‚ this is about room temperature. It is seen that in the TNZ‚ the metabolic rate decreases from about 1.75 to 1 (Fig 1). During the
