What is the Electron Transport Chain? Electron transport chain Definition The electron transport chain is a series of protein complexes and molecules located in membranes, where electrons are transferred through redox reactions to generate a proton gradient that drives ATP synthesis via oxidative phosphorylation. Electron Transport Chain Animation Video Fundamentals of the Electron Transport Chain … Read more

What is Oxidative Phosphorylation? Definition of Oxidative Phosphorylation Oxidative phosphorylation is a metabolic process that occurs in the mitochondria, where energy derived from the electron transport chain is used to produce adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate, with oxygen acting as the final electron acceptor. Sites of oxidative phosphorylation in ETC … Read more

What is Photosystem I (PS1)? Definition of Photosystem I (PS1) Photosystem I (PSI) is a crucial protein complex in oxygenic photosynthesis, primarily found in algae, plants, and cyanobacteria. It functions by capturing light energy to drive the transfer of electrons across the thylakoid membrane, from plastocyanin to ferredoxin. This process contributes to the synthesis of … Read more

What is Ethanol Metabolism? Definition of Ethanol Metabolism Ethanol metabolism is the biological process by which the body breaks down and eliminates ethanol, primarily in the liver, through a series of enzymatic reactions that convert it into less toxic compounds, ultimately producing energy and releasing water and carbon dioxide. Location of Ethanol Metabolism Distribution of … Read more

What is Anabolism? Definition of Anabolism Anabolism is the metabolic process in which complex molecules are synthesized from simpler ones, typically requiring an input of energy. Stages of Anabolism Anabolism, a fundamental metabolic pathway, involves the synthesis of intricate molecules from simpler precursors. This process is central to the growth and maintenance of cells and … Read more

What is Cellular Respiration? Cellular respiration is a vital metabolic process that occurs within cells, enabling the conversion of energy stored in carbohydrates into energy carriers, most notably adenosine triphosphate (ATP). Cellular respiration can occur in the presence or absence of oxygen. When oxygen is available, it is referred to as aerobic respiration. This process … Read more
