A metabolic pathway is a series of connected chemical reactions that feed one another. The pathway takes in one or more starting molecules and, through a series of intermediates, …

Metabolism is a set of chemical reactions that interconnect in a series of pathways. It is a balancing act between the building and breakdown of molecules in the body.

Together, catabolism and anabolism represent the two sides of metabolism, which encompasses all the chemical reactions and processes that occur within cells to maintain life.

Introduction Let’s imagine that you are a cell. You’ve just been given a big, juicy glucose molecule, and you’d like to convert some of the energy in this glucose molecule into a more …

This strategy is used in many metabolic pathways in the cell, providing a way for the energy released by converting ATP to ADP to drive other reactions forward.

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs …

How, then, are the other components of food – such as proteins, lipids, and non-glucose carbohydrates – broken down to generate ATP? As it turns out, the cellular respiration …

Some of your body's metabolic reactions, like the ones that make up cellular respiration, extract this energy and capture part of it as adenosine triphosphate (ATP). This energy-carrying …

Sulfur and nitrogen metabolism Some bacteria and archaea have metabolic pathways that allow them to metabolize nitrogen and sulfur in ways that eukaryotes cannot.

Explore the regulation of metabolic pathways, a crucial balancing act in the body. Dive into glycolysis and gluconeogenesis, and understand when each pathway dominates.
