Determining Basal Energy Expenditure and the Capacity of Thermogenic Adipocytes to Expend Energy in Obese Mice
Published on: November 11, 2021
Summary
All vital functions require energy, but organisms can preserve life with minimal energy. This study explores "life without energy" through comparative physiology.
Area of Science:
- Physiology
- Comparative Physiology
- Bioenergetics
Background:
- Vital activity in organisms necessitates significant energy expenditure for functions like respiration, circulation, and movement.
- Maintaining viability can be achieved with remarkably low energy consumption, a state termed 'life without energy'.
Purpose of the Study:
- To investigate the phenomenon of 'life without energy' in living organisms.
- To analyze the comparative physiological aspects of minimal energy preservation.
Main Methods:
- Comparative physiological analysis of different organisms.
- Examination of energy requirements for vital functions versus viability preservation.
Main Results:
- Organisms exhibit a spectrum of energy dependency, with some capable of prolonged survival using minimal energy.
- The energy cost of maintaining basic viability is substantially lower than that of active vital functions.
Conclusions:
- Life without energy represents a unique biological strategy for survival under low-energy conditions.
- Understanding this phenomenon offers insights into the fundamental principles of bioenergetics and organismal resilience.

00:51Energy Budgets and Reproductive Strategies
Organisms must balance energy intake with the energy required for growth, maintenance, and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species reproduce only once in their lifetime, often investing most available resources into that single reproductive event. Iteroparous species, by contrast, reproduce multiple times over their lifetimes, typically allocating fewer resources to any single...
01:24Metabolic States of the Body: Fasting and Starvation
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
02:27Energy Basics
Chemical reactions, such as those that occur when you light a match, involve changes in energy as well as matter.
01:19Energy Balance
The human body gets energy from the three macronutrients: carbohydrates, proteins, and fats. Energy is released when the chemical bonds in the organic compounds present in the food are broken down. The energy content of food is measured in kilocalories (kcal), defined as the amount of heat required to raise the temperature of one kilogram of water by one degree Celsius. This value is determined by measuring the temperature change of the water surrounding a calorimeter after the complete...
00:48Optimal Foraging
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.
00:54Conservation of Energy
The terms 'conserved quantity' and 'conservation law' have specific scientific meanings in physics, which differ from the meanings associated with their everyday use. For example, in everyday usage, water could be conserved by not using it, by using less of it, or by re-using it. However, in scientific terms, a conserved quantity of a system stays constant, changes by a definite amount that is transferred to other systems, and is converted into other forms of that quantity. In the scientific...
