Comparing the BMR of Mice and Humans

Summary The respiratory system is responsible for coordinating the gas exchange between the body and the external environment. The difference in respiratory rate indirectly affects basal metabolic rate (BMR) by providing essential components of adenosine triphosphate (ATP) formation (Williams et al, 2011). Gas exchange of 2 25 g and 27 g mice (muscle) was measured and fasted at room temperature, low temperature (8 ° C.) and recorded using a volumeter at room temperature.

BMR is the main way humans consume energy. In other words, if dietary intake does not change accordingly, changes in BMR may lead to changes in weight (1). Thyroid hormone is the main regulator of BMR; the higher the TSH, the lower the BMR (2, 3). When taking thyroid medication, BMR is very sensitive to slight changes in drug levels (4). Thyroid hormone increases the production of ATP (adenosine triphosphate), the main energy chemical in the body (5, 6). This process is done in a cellular energy plant called mitochondria (7), the number of T3 and the balance between T3 and T4 determine the amount of ATP produced.

Calories are more than just sports. It consists of two things - rest energy consumption, or basal metabolic rate (BMR) and exercise. Assuming zero motion, the average BMR is 2000 calories per day. This energy is used by the heart, lungs, kidneys, body temperature and so on. BMR is not affected by consciousness. You can not decide that your heart will draw more blood. You can not "resolve" to produce more body temperature. Not much will will not let your kidneys consume more energy

What impacts BMR? To some extent, BMR is genetic - through the gene transfer we get from our parents. Sometimes health problems affect someone's BMR. But people can change their BMR in several ways. For example, by exercising more, a person burns more calories during extra activity and becomes more healthy, thereby increasing his or her BMR. BMR is also affected by body composition - people with high muscle and low fat usually have higher BMR. Most metabolic diseases include abnormal levels of enzymes or hormones, or how these enzymes or hormones act. When the metabolism of body chemicals is disturbed or incomplete it may cause the accumulation of toxic substances in the body or the lack of material necessary for normal body function, both of which cause serious symptoms maybe.
