The major hypothesis is that African Americans have a smaller mass of the most metabolically active organs (ie, liver, spleen, kidneys, heart, and brain)—and therefore a lower proportion of body mass as high-metabolic-rate (HMR) tissues—than do whites.
What is the meaning of metabolically active tissue?
Muscle is metabolically active tissue. This means that it utilizes calories to work, repair, and refuel itself. … Muscle is made up of what is called metabolically active tissue which means that it requires energy to be built, used and maintained.
Which organ has the highest metabolic rate and uses the most oxygen?
In addition, the kidneys use up about 7.2%, and the skin uses 4.8% The rest of the body consumes the remaining 17.6% of the oxygen. Oxygen use can also be measured per 100 gm of an organ to indicate concentrations of use; as such, heart usage is highest, followed by the kidneys, then the brain, and then the liver.
How do you activate metabolically active tissues?
Eating plenty of protein is the best way to give your metabolism a diet-related bump. Protein not only helps you build and maintain metabolism-revving muscle tissue, but it also temporarily increases your metabolism after you eat it.
What body tissue has a huge difference in the resting vs active metabolic rate?
Here’s why: One of the variables that affect your resting metabolic rate is the amount of lean muscle you have. At any given weight, the more muscle on your body, and the less fat, the higher your metabolic rate. That’s because muscle uses a lot more energy than fat while at rest (see the graphic in section one).
What happens when energy availability fails to keep up with energy demands?
Lactic Acid Accumulation
If the respiratory or circulatory system cannot keep up with demand, then energy will be generated by the much less efficient anaerobic respiration. … Pyruvate is continually processed into lactic acid. With pyruvate accumulation, lactic acid production is also increased.
What is metabolism rate of human body?
An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day. The rate of energy expenditure is usually lowest in the early morning.
What organ uses most energy?
May is the Month of the Brain, our most energy-consuming organs. Representing only 2% of the weight of an adult, the brain consumes 20% of the energy produced by the body.
Which part of the human body requires more oxygen?
Answer and Explanation: The liver, brain, and heart consume the most oxygen in the body. The liver consumes 20.4%, the brain 18.4%, and the heart 11.6%.

What are the 3 metabolic types?
The three main body types (or somatotypes) are endomorph, ectomorph and mesomorph. You’ll probably identify most with one of these, or you may see yourself reflected in a combination of two.

Which body tissue is the least metabolically active?
Organ-tissue level modeling
Four metabolically active organs, brain, liver, kidneys and heart, have high specific resting metabolic rates when com- pared with the remaining less-active tissues, such as skeletal muscle, adipose tissue, bone and skin (13).
