Mice oxygen consumption ordinate - Essay ExampleWarm-blooded wolfs proceed thermic homeostasis via internal metabolous processes hence, endotherms can remain active over a broad range of ambient temperature (Stanier 79). 2 Define metabolic valuate Metabolic rate refers to the amount of energy utilized in a set period. Metabolic rate represents the pace at which energy can be utilized by an organism and encompasses the integration of all catabolic energy transformations in the body, as well as the intensity and speed of life itself. The metabolic rate may be enhanced by several(prenominal) processes of considerable ecological significance including tissue synthesis, food processing, and physical activity. The metabolic rate stiff closely related to the rate of ATP production measured by cellular respiration (oxygen consumption or carbon dioxide production. Metabolism represents the set of essential chemical transformations in the cells of living organisms. Metabolism also refer s to all chemical reactions that manifest within living organisms including transport of substances (Cannon and Nedergaard 242). 3 Factors that affect metabolic rate The metabolic rates can be essentially determined by relatively few factors, namely temperature, phylogenetic affinities, and mass. The body temperature possesses pervasive impacts on biologic processes via the influence of temperature on the activity of metabolically significant enzymes. The metabolic rates double or triple in the event that body temperature increases by 10C. The absolute levels of metabolism that the temperature levels establish may be subject to acclamatory or evolutionary changes through the alteration of enzyme structure or composition. In endotherms, the impacts of the core thermal dependence may be surpassed by the physiological regulation of body temperature, which is energetically expensive ((Navas and Jose? 13). One of the primary factors impacting on metabolic rate is son size or body mass. The metabolic rate interspecifically relates with body mass. Individuals with greater body weight manifest a higher resting metabolism relative to small individual since their body would have to work harder to support and sustain the extra weight. This theory stipulates that, endothermic animals must metabolically generate enough body light to balance the heat lost via their body surface if they were to maintain a constant body temperature. Phylogeny The metabolic level differs among taxa, whereby the phylogenetic history of an animal determines the rate of energy expenditure (Navas and Jose? 15). Moreover, men usually possess less body fat and much muscles relative to women of the same weight and age, which leads to burning of more calories. As people get older, the size of the muscle tends to reduce, which in turn slows down calories burning. 4 How metabolic rate is dependent on the ambient remote temperature The temperature of an animal relies on the amount of heat containe d within the animals body. Animals can absorb or lose heat from or to the environment via several processes such as convection, conduction, radiation, and evaporation. The amount of heat transferred into or out of an animal hinges on the surface area, heat
