Organs energy expenditure

Table 2.8 Metabolic rate of different organs or tissues in an adult human and contribution of the different organs and tissues to whole-body resting energy expenditure, (REE) in an adult male, female and a six month old child...

Nutrition is also of vital importance in infancy the synthesis of structural components containing carbohydrates, proteins, nucleic acids and phospholipids takes place at high rates as organs develop and mature. Carbohydrate and fat are required for provision of energy and energy expenditure in the newborn is three to four times higher than in the child. 

The energy intake by an organism plus or minus any change in body mass or composition. Lifson and McClin-tock introduced the use of doubly labeled water ( H20 and H2 0) to estimate energy expenditure. In this strategy, is lost from the body as labeled water and carbon... 

A small organism has a heat loss of -< = 1.65 W and performs external work W = 0.025 Nm/s. Calculate that part of the total energy expenditure that originates from its internal circulation, which involves the pumping of 122mL/min of fluid against a pressure drop of 3.4 kPa with a net chemo-mechanical efficiency of 12%. 

Molecule and product suppliers complement one another in their implementation of nanotechnology in order to equip nanoparticles with functions that could not have been achieved with the technologies available to us in the past. For instance, the principle of self-organization in the nanometer range is based on functional molecule groups that form weak, non-covalent interactions. This allows an automatic formation of new functional structures without any large energy expenditure.
