Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

What is Metabolism?

2019
Overview Metabolism represents all of the chemical activity in a cell, including reactions that build molecules (anabolism) and those that break molecules down (catabolism). Anabolic reactions require energy, whereas catabolic reactions provide it. Thus, metabolism describes how cells transform energy through a variety of chemical reactions, which are often made more efficient with the help of enzymes.

In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller components. Respectively, the reactions responsible for this are referred to as anabolic and catabolic. These reactions require or produce energy typically in the form of a “high-energy” molecule called ATP. Together, these processes make up “Cell Metabolism,” and are hallmarks of healthy, living cells.JoVE’s introduction to cell metabolism briefly...
FAQs
The liver serves as the central regulator of copper balance by directing copper through specialized transport pathways. These pathways help determine whether copper is transferred for tissue use, retained within the body, or eliminated through bile. This hepatic control is especially important because disruption can contribute to clinically recognized copper disorders.
Copper supports cellular functions after tissues incorporate it into copper-dependent enzymes. These enzymes contribute to cellular energy production, connective tissue formation, and antioxidant defense, so copper availability affects several physiological systems at once. Studying this incorporation helps connect abnormalities in copper handling with neurological, hepatic, and systemic consequences.
After absorption in the intestine, copper binds to transport proteins that help move it through the body and deliver it to tissues. This organized transport allows copper to reach sites where it can be incorporated into enzymes rather than remaining randomly distributed. The process links absorption with tissue function and regulated elimination.
Wilson disease and Menkes disease are medically important examples of abnormal copper metabolism, but the overview does not imply that they are assessed identically. Understanding the underlying transport and regulatory system gives clinicians a framework for recognizing copper imbalance, interpreting relevant findings, and supporting disease diagnosis and management.
Copper and ceruloplasmin measurements provide information used in evaluating copper metabolism. Their interpretation supports the medical assessment of disorders such as Wilson disease and Menkes disease, rather than serving as isolated descriptions of intake or absorption. These measurements are therefore relevant to diagnostic reasoning and to monitoring questions involving copper imbalance.
Copper metabolism provides a framework for investigating how imbalance may affect multiple organ systems. The overview identifies neurological, hepatic, and systemic effects as important research areas, while the liver remains central because it regulates copper handling. This combination connects molecular transport pathways with broader questions about disease mechanisms and clinical outcomes.
