Summary
Currents in biology, like electron and proton flow in mitochondria, follow electrical laws. Chemiosmotic theory is incorrect; an electro-osmotic theory is needed for ATP production.
Area of Science:
- Electrophysiology
- Bioenergetics
- Biophysics
Background:
- Current flow in technology relies on Maxwell-Ampere law and magnetism.
- Biological systems, such as mitochondria and nerve cells, utilize electrical currents carried by electrons and ions.
- Analyzing individual charges is computationally infeasible for understanding current flow.
Purpose of the Study:
- To highlight the necessity of applying electrical circuit laws to biological current flow.
- To propose an electro-osmotic theory for ATP production, replacing the current chemiosmotic theory.
- To demonstrate the applicability of circuit analysis to biological systems like mitochondria.
Main Methods:
- Application of Kirchhoff's current law and its generalizations to biological systems.
- Utilizing the Hodgkin-Huxley-Katz (HHK) equation for modeling short electrical systems.
- Integrating classical chemical reaction descriptions with circuit analysis for computable models.
Main Results:
- Electron and proton flows in ATP generation must be analyzed as electrical currents governed by circuit laws.
- The proton motive force is a component of the electrochemical potential, analogous to other ionic currents.
- Chemiosmotic theory is fundamentally flawed by ignoring established laws of current flow.
Conclusions:
- ATP production in mitochondria and chloroplasts requires analysis using current laws for electron and proton flow.
- An electro-osmotic theory, consistent with electrodynamics and including proton motive force, should replace chemiosmotic theory.
- Circuit analysis provides a more accurate framework for understanding bioenergetic processes involving charged particle movement.

Electrochemical Gradient and Channel Proteins: An Overview
2.6K
An electrochemical gradient is a fundamental concept in biology and chemistry. It regulates the movement of ions across cell membranes. This movement is influenced by two factors:
The electrical gradient: The electrical gradient across cell membranes refers to the difference in electric charge between the inside and outside of a cell. This difference drives the movement of ions towards or away from the cells. For instance, if the inside of the cell is more negatively charged relative to...

Electromotive Force

Electricity is generated by either electrons or ions flowing through a solution or a conducting medium. This flow of electrons or specifically electrical charge is defined as an electric current. When electrons move through a wire, they generate an electric current. It can be recalled that in a redox reaction, electrons are lost and gained. In the spontaneous redox reaction of zinc with copper, when zinc is immersed in a copper ion solution, a transfer of electrons from one...

Controlled-Potential Coulometry: Electrolytic Methods
266
Controlled-potential coulometry, also known as potentiostatic coulometry, employs a three-electrode system in which the working electrode's potential is precisely regulated using a potentiostat. Platinum working electrodes are utilized for positive potentials, while mercury pool electrodes are favored for extremely negative potentials. The platinum counter electrode is separated from the analyte using a membrane or salt bridge to avoid interference in the analysis.

Action Potential
8.3K
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the release of neurotransmitters at axon terminals, thereby transmitting information to the nervous system. An action potential is a specific "all-or-none" change in membrane potential that results in a rapid spike in voltage.
Membrane potential in neurons
Neurons typically have a resting membrane potential of about -70 millivolts (mV). When they receive...

Facilitated Transport
13.7K
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...
