Non-equilibrium in the Cell01:16

Non-equilibrium in the Cell

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...

Cell Potential and Free Energy

Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...

Area of Science:

  • Biophysics
  • Cell Biology
  • Biochemistry

Background:

  • Cell-cell communication is crucial for multicellular organisms.
  • Existing mechanisms like diffusion have limitations in speed and efficiency.
  • The formation of supramolecular structures in biological systems is an area of interest.

Purpose of the Study:

  • To investigate the properties and potential functions of newly identified 'strings' in homochiral solutions.
  • To determine if these strings can mediate cell communication.
  • To compare the efficiency of string-mediated communication with diffusion.

Main Methods:

  • Formation and characterization of isometric strings in homochiral solutions (10(-3)-10(-2) M).
  • Measurement of macroscopic properties including strength and end-charge.
  • Assessment of cellular transport capabilities and velocity.
  • Comparative analysis of information exchange efficiency versus diffusion.

Main Results:

  • Isometric strings with high aspect ratios (10(1)-10(5)) were formed.
  • These strings exhibit significant strength and electrostatic forces.
  • Strings demonstrated the capacity to transport cells at approximately 1 cm/sec.
  • String formation provides a directional, error-resistant, and efficient information exchange mechanism.

Conclusions:

  • Cellular strings represent a novel mechanism for rapid and efficient cell-cell communication.
  • String-mediated transport is superior to diffusion in terms of speed and substance utilization.
  • These findings suggest that strings and similar structures, like cytonemes, are vital for intercellular interactions.
