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.

An Introduction to Cell Metabolism

2023
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...

Metabolic Labeling

2023
Metabolic labeling is used to probe the biochemical transformations and modifications that occur in a cell. This is accomplished by using chemical analogs that mimic the structure of natural biomolecules. Cells utilize analogs in their endogenous biochemical processes, producing compounds that are labeled. The label allows for the incorporation of detection and affinity tags, which can then be used to elucidate metabolic pathways using other biochemical analytical techniques, such as SDS-PAGE...

FAQs
Metabolic adaptation depends on coordinated control rather than a single metabolic switch. Enzyme activity can change the rate of existing pathways, while altered gene expression can modify pathway capacity over time. Substrate availability and hormonal signaling add further control, allowing cells to redirect nutrient use or storage as conditions change.
Substrate availability determines which fuel-processing options remain feasible. When glucose supply, stored nutrients, or other available substrates change, cells can adjust the relative use of glucose oxidation, fat utilization, and energy storage. This regulation helps align energy production with present nutrient conditions, rather than maintaining one fixed pattern of fuel use.
Limited oxygen creates a distinct constraint because energy production must be adjusted under reduced oxygen availability. In this setting, metabolic adaptation helps preserve cellular function by changing how available nutrients are handled. Studying this response is relevant to biology because it connects environmental conditions with cellular energy management and survival.
Fasting and exercise provide useful biological contexts for examining metabolic adaptation because each changes the demands placed on energy balance. Stress and limited oxygen offer additional contexts, allowing investigators to compare how internal and environmental challenges influence fuel selection, pathway regulation, and cellular function. Together, these conditions reveal the breadth of metabolic flexibility.
Research on metabolic adaptation can examine changes in enzyme activity, gene expression, substrate availability, and hormonal signaling under conditions such as fasting, exercise, stress, or limited oxygen. Comparing these regulatory features with changes in glucose oxidation, fat utilization, or energy storage can show how cells and organisms adjust their metabolism.
Metabolic adaptation research informs physiology, development, and disease biology by linking regulatory changes to altered energy use and storage. Its relevance extends to diabetes, obesity, and cancer, where metabolic regulation is important to disease research. Findings can also support research on nutrition, therapeutics, and individualized health strategies, connecting basic biology with potential applications.
