the LCT and 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)

effects of TSH and thyoxine on metabolic rate are investigated. Hypothesis: With the information given‚ we tested the effects of given hormones on the body by using virtual rats. We expect to see a greater metabolic rate for the normal rat as opposed to the thyroidectomized rat. The hypox rat is expected to have the lowest metabolic rate. Metabolic rate will increase once thyroxine is injected. TSH will increase the metabolic rate of all the rats with

Metabolic rate refers to the “amount of oxygen consumed by the body cells” (Farlex‚ n.d.). it can be affected by numerous factors‚ some of which being the mass of the animal‚ its physical activity and temperature. Invertebrates are able to live in highly variable conditions due to their metabolism having evolved over time. Homeotherms are animals that are able to maintain a specific body temperature without relying on the temperature from its surroundings. Poikilotherms on the other hand do the exact

understand their metabolic process at various temperatures. Other studies show that although poikilotherms are viable at varying temperatures some organisms like the salmon still struggle to survive or succeed as temperature fluctuate (Brett 1971). The fish loses energy and at different stages of their life‚ they have different temperature tolerances that ultimately regulate the fish species overall population and success (Bisson and Davis 1976).

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age

BIO 211 Lab Section 11 February 15‚ 2012 Effects of Temperature on Enzymatic Activity Abstract Temperature is a measure of kinetic energy. As this movement increases‚ collision rate and intensity‚ and therefore reaction rates‚ increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction

Introduction: Basal Metabolic Rate has been defined as the minimum amount of energy needed by an animal to maintain the basic functions of survival (such as breathing). Several factors including age‚ gender‚ weight‚ and exercise affect the BMR. "BMR increases with increasing muscle tissue" therefore‚ exercising will enhance BMR while with increasing age‚ BMR is reduced (Scott‚ 2008). Also gender differences exist between males and females; it has been shown that males have higher BMRs

THE GREAT METABOLIC RACE INTRODUCTION During exercise‚ carbohydrates and lipids are required in order to provide energy for the working body. The inherent reduced nature of these compounds allows for partial or complete oxidation in extracting energy in the form of adenosine triphosphate (ATP). The varying chemical structure of the macromolecules evokes different processes for their complete utilisation. This paper seeks to expound on the mobilisation of these fuels‚ the biochemical pathways that
