metabolism

/məˈtæb.ə.lɪ.z(ə)m/Roman

English meaning: Metabolism

English Definition

(English)

Metabolism encompasses all biochemical processes in cells: cellular respiration converts glucose to ATP (energy), anabolic pathways build proteins and nucleic acids, and catabolic pathways break down fats, carbohydrates, and proteins. Metabolic disorders include diabetes (glucose metabolism), thyroid disease (energy metabolism), and metabolic syndrome. Basal metabolic rate (BMR) is the energy needed to sustain basic life functions at rest.

English Definition

The totality of chemical reactions in living organisms that sustain life — including catabolism (breaking down molecules to release energy) and anabolism (building molecules using energy). Metabolic rate determines how quickly an organism burns energy.

Example

Exercise accelerates metabolism by increasing the demand for ATP, forcing cells to burn more glucose and fat — which is why regular physical activity is central to managing weight and metabolic health.

In English: Physical exercise raises metabolic rate, increasing energy expenditure and improving metabolic health.

Synonyms

  • biochemical processes
  • cellular chemistry

Literary Heritage

Considering how common illness is, how tremendous the spiritual change that it brings, how astonishing, when the lights of health go down, the undiscovered countries that are then disclosed.
