Electron carriers are molecules that transport electrons during metabolic processes, playing a crucial role in energy production and transfer within cells. They facilitate the conversion of nutrients into usable energy by shuttling electrons between different biochemical pathways, such as the electron transport chain in cellular respiration.

Metabolic processes are the chemical reactions that occur within a living organism to maintain life, involving the conversion of food to energy, building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes. These processes are divided into catabolic pathways that break down molecules to produce energy and anabolic pathways that use energy to synthesize components of cells and tissues.

metabolic processes

Energy production is the process of generating energy from primary sources such as fossil fuels, nuclear, and renewable resources to meet human consumption needs. It involves complex systems and technologies that convert these sources into usable electricity or fuel, impacting economic, environmental, and social dimensions globally.

energy production

Energy transfer is the process by which energy moves from one system or object to another, often changing form in the process. This fundamental concept is crucial for understanding various physical phenomena, from biological processes to mechanical systems and thermodynamics.

Biochemical pathways are sequences of chemical reactions occurring within a cell, facilitated by enzymes, which convert substrates through a series of intermediates into final products. These pathways are crucial for maintaining cellular functions and homeostasis, and they include processes such as metabolism, signal transduction, and energy transfer.

biochemical pathways

The electron transport chain is a series of protein complexes located in the inner mitochondrial membrane that facilitates the transfer of electrons from electron donors to electron acceptors via redox reactions. This process generates a proton gradient across the membrane, ultimately driving the synthesis of ATP through oxidative phosphorylation.

Cellular respiration is a metabolic process by which cells convert biochemical energy from nutrients into adenosine triphosphate (ATP), releasing waste products. It involves a series of redox reactions and occurs in three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.
