What are the differences between catabolism and anabolism?

Posted August 30, 2024


Answer

Basis of differentiation 

Catabolism

Anabolism

Definition 

Is a metabolic process that breaks down large, complex molecules into small molecules that are easier to absorb



Is a metabolic process in which simple substances are transformed into complex molecules – the process essentially builds molecules required for the body’s functionality

Type of reaction

Is an exergonic reaction

Is an endergonic reaction

Energy & Heat generation/requirement

The process releases ATP energy and does not require any heat 

The process requires ATP energy as it absorbs heat

Energy conversion 

Potential energy is converted into kinetic energy

Kinetic energy is converted into potential energy

Oxygen utilization 

Requires more oxygen 

Requires less oxygen 

Metabolic phase 

Is considered the destructive phase of metabolism

Is considered the constructive phase of metabolism

Hormones Responsible

  • Cortisol
  • Adrenaline
  • Glucagon
  • Cytokine
  • Growth hormones
  • Estrogen
  • Testosterone
  • Insulin 

Functionality

Is crucial for performing various activities in living entities

Is crucial for growth, maintenance, and storage

Active phase

Is functional during activities

Is functional during rest or sleep

Effect on the human body

  • Burns calories and fats
  • Uses the foods stored within cells to generate energy
  • Furnishes and repairs tissues
  • Increases muscle mass
