Entropy within the Cell01:22

Entropy within the Cell

10.9K
A living cell's primary tasks of obtaining, transforming, and using energy to do work may seem simple. However, the second law of thermodynamics explains why these tasks are harder than they appear. None of the energy transfers in the universe are completely efficient. In every energy transfer, some amount of energy is lost in a form that is unusable. In most cases, this form is heat energy. Thermodynamically, heat energy is defined as the energy transferred from one system to another that...

Non-equilibrium in the Cell

4.6K
An important concept in studying metabolism and energy is that of chemical equilibrium. Most chemical reactions are reversible. They can proceed in both directions, releasing energy into their environment in one direction, and absorbing it from the environment in the other direction. The same is true for the chemical reactions involved in cell metabolism, such as the breaking down and building up of proteins into and from individual amino acids, respectively. Reactants within a closed system...

Energy Budgets00:51

Energy Budgets

9.6K
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, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...

Diversity of Protists IV01:27

Diversity of Protists IV

82
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Trophic Efficiency00:46

Trophic Efficiency

21.1K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Cell Diversity

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

Area of Science:

  • Thermodynamics
  • Biophysics
  • Systems Biology

Background:

  • Organisms require energy for life processes and to counteract entropy.
  • Dissipative structure theory provides a thermodynamic framework for understanding life, but biological systems are highly complex.
  • Simulated models are crucial for studying fundamental principles in complex biological systems.

Purpose of the Study:

  • To investigate the relationship between the dynamical stability of simulated organism-like foraging behavior and entropy production.
  • To explore how coordination between metabolic and behavioral processes affects thermodynamic properties.
  • To evaluate the validity of the maximum entropy production principle in a simplified biological model.

Main Methods:

  • Development of a simulated 1D chemical dissipative structure functioning as a proto-cell.
  • Implementation of resource collection (foraging) and a nonlinear reaction network (metabolism) within the proto-cell.
  • Analysis of the correlation between the stability of swimming and chemotaxis dynamics and the rate of entropy production.

Main Results:

  • A relationship was observed between dynamical steady states and entropy production.
  • The coordination between foraging and metabolic processes was found to tune this relationship.
  • The study provides evidence both supporting and contradicting a formulation of the maximum entropy production principle.

Conclusions:

  • The interplay between an organism's behavior and its metabolism significantly impacts its thermodynamic efficiency.
  • The findings challenge a simplistic application of the maximum entropy production principle to biological systems.
  • This research contributes to understanding the fundamental thermodynamic underpinnings of life.
