What is Energy?

59.6K
The universe is composed of matter in different forms, and all forms of matter contain energy.  The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Resting Membrane Potential

22.1K
The relative difference in electrical charge, or voltage, between the inside and the outside of a cell membrane, is called the membrane potential. It is generated by differences in permeability of the membrane to various ions and the concentrations of these ions across the membrane.
The Inside of a Neuron is More Negative
The membrane potential of a cell can be measured by inserting a microelectrode into a cell and comparing the charge to a reference electrode in the extracellular fluid. The...

Resting Potential Decay01:15

Resting Potential Decay

6.5K
The resting membrane potential of a neuron (-70mV) is sustained due to the selective ion permeability of the membrane. At the resting potential, the membrane is slightly permeable to ions like sodium (Na+) and chloride (Cl−) and highly permeable to potassium ions (K+). Differences in the ions' concentration inside the cell compared to the outside are maintained by membrane transport proteins like channels and pumps.
At rest, the K+ is the main ion that moves across the membrane...

Pressure Variation in a Fluid at Rest01:11

Pressure Variation in a Fluid at Rest

856
In a fluid at rest, the pressure at any point beneath the fluid surface depends solely on the depth, not on the container's shape or size. This principle, known as hydrostatic pressure, arises because, in stationary fluids, there is no acceleration, meaning the forces within the fluid balance out. Only vertical forces, caused by the weight of the fluid above, contribute to pressure changes with depth.
When measuring pressure at two different levels within the fluid, the difference in...

Area of Science:

  • Nutrition and Metabolism
  • Human Physiology

Background:

  • Resting energy expenditure (REE) is crucial for determining accurate energy requirements.
  • Establishing normative REE data across diverse demographics is essential for clinical and research applications.

Purpose of the Study:

  • To systematically measure and analyze resting energy expenditure (REE) in a large cohort stratified by age and sex.
  • To establish reference values for REE and REE per kilogram body weight.

Main Methods:

  • Utilized a portable calorimeter (Metavine) for systematic REE measurements.
  • Collected data from 6498 subjects, stratified by sex and age (1-year increments), with a minimum of 10 subjects per group.
  • Analyzed REE and REE/kg to determine standard deviations and age/sex-specific trends.

Main Results:

  • Observed standard deviations for REE and REE/kg ranging from 20-25% across different age and sex groups.
  • Found that REE/kg remained relatively stable after 15 years of age for both males and females.
  • Estimated the average REE/kg to be approximately 29 kcal/kg in adolescents and adults.

Conclusions:

  • The study provides valuable normative data for resting energy expenditure across a wide age and sex spectrum.
  • Findings indicate a consistent REE/kg around 29 kcal/kg post-adolescence, aiding in energy requirement calculations.
  • The systematic measurement approach ensures reliable data for nutritional assessment and metabolic research.
