Definition

1. Noun:
   • The breakdown of complex substances into simpler ones in living organisms, accompanied by the release of energy: This is the primary biological process of catabolism, where molecules like carbohydrates, fats, and proteins are broken down to provide energy and basic building blocks for the organism.

Usage

• Noun:
  • Destructive metabolism is a fundamental process that provides the energy necessary for all cellular activities.
  • During exercise, the rate of destructive metabolism increases to meet the body's heightened energy demands.

Examples

• Noun:
  • The digestion of food is a clear example of destructive metabolism, where complex nutrients are broken down into simpler molecules.
  • In cellular respiration, destructive metabolism of glucose releases energy stored in its chemical bonds.

Advanced Usage

• "The destructive metabolism of lipids": This phrase specifies the catabolic breakdown of fat molecules.
  • The destructive metabolism of lipids provides a substantial amount of energy during prolonged fasting.

Variants and Related Words

• Catabolism (n): The scientific synonym for destructive metabolism; the set of metabolic pathways that break down molecules.
  • Catabolism and anabolism are the two complementary phases of metabolism.
• Catabolic (adj): Relating to or characterized by catabolism.
  • The catabolic state of muscle tissue occurs during intense physical stress.

Synonyms

• Catabolism: The breakdown of complex molecules in living organisms to form simpler ones, with the release of energy.
• Dissimilation: A biological process involving the breakdown of complex substances.

Antonyms

• Anabolism: The phase of metabolism in which simple substances are synthesized into the complex materials of living tissue (constructive metabolism).
• Biosynthesis: The production of complex molecules within living organisms or cells.
