What is Metabolism?
0 Views •
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.

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.

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...

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
FAQs
Nutrient availability changes which substrates a biological system can use and how it produces energy. Comparing conditions with different nutrient supplies can therefore reveal shifts in substrate use, energy production, and cellular activity. These changes help researchers connect environmental or nutritional conditions with broader effects on tissue function, growth, stress responses, or physiology.
Hormonal responses provide regulatory signals that help distinguish fed and fasting conditions. Rather than examining nutrient availability alone, researchers can assess how these signals accompany changes in energy production, substrate use, and biochemical pathway activity. This integrated view helps explain how metabolism is regulated and how altered signaling may contribute to metabolic dysfunction.
Different biological levels can show distinct consequences of the same metabolic shift. A cellular comparison may emphasize activity or pathway changes, whereas tissue and organism-level comparisons can reveal effects on growth, physiology, or stress responses. Examining these levels together helps researchers determine whether an observed difference is local, systemic, or related across scales.
Researchers first establish the metabolic conditions to compare, such as fed and fasting states or other differences in nutrient availability. They then examine energy production, substrate use, regulatory signals, and relevant biological responses under each condition. Organizing observations around the same variables allows differences between states to be interpreted systematically rather than as isolated measurements.
State-to-state differences can indicate which biochemical pathways or regulatory processes change under particular conditions. They may also clarify relationships between environmental conditions and physiology, including altered cellular activity, growth, or stress responses. Interpreting these patterns can help identify metabolic dysfunction and provide a basis for investigating how biological systems respond to changing energetic demands.
This approach supports research into nutrition, exercise, metabolic disorders, and therapeutic strategies. In each setting, comparing conditions can show how metabolism responds to different energetic or physiological circumstances. The resulting information may help characterize disease-related dysfunction, evaluate biologically relevant responses, and guide investigations of strategies intended to influence metabolic processes.
