Difference between catabolism and metabolism

Main difference

The main difference between catabolism and metabolism is that catabolism is the mechanism of division of macromolecules into smaller molecules, while metabolism is the complete set of reactions of catabolism and anabolism …

Catabolism versus metabolism

Catabolism are constructive biochemical reactions; on the other hand, metabolism is both constructive and destructive biochemical reactions. Catabolism is the process by which energy released during chemical reactions; on the other hand, metabolism is the process in which energy is absorbed or released during chemical reactions.

Catabolism is the type of biochemical process in which larger molecules become smaller molecules; on the other hand, metabolism is the biochemical process in which both reactions occur, whether it is the breakdown of larger molecules into smaller molecules or the joining of smaller molecules into larger molecules. Catabolism is the only destructive process; On the other side of the coin, metabolism is a destructive and constructive process.

Catabolism occurs only in the presence of oxygen; on the other hand, metabolism occurs in the presence and absence of oxygen. Catabolism uses only catabolic hormones; on the other hand, metabolism uses catabolic and anabolic hormones. The catabolism process occurs mainly in the most strenuous bodily activities; On the other side of the coin, the metabolism is efficient both at rest and in the functional activities of the body.

Catabolism occurs in the processes of digestion, respiration, and excretion; on the other hand, metabolism occurs in protein synthesis, glycogen synthesis, digestion, respiration, photosynthesis in plants, etc. Catabolism is the aerobic process, while metabolism is both an aerobic and anaerobic process. Catabolism is the exergonic process; on the opposite side, metabolism is endergonic and exergonic reactions.

Comparative chart
Catabolism Metabolism
Catabolism is the process by which larger molecules break down into smaller molecules. Metabolism is the complete package of biochemical reactions.
Energy
Energy releases during the process Energy absorbed or released during the process
Aerobic or Anaerobic
It is the aerobic process in which oxygen is needed. Includes both the aerobic and anaerobic process in which oxygen may or may not need
Functional
It is functional only in strenuous bodily activities. It is functional both at rest and in other bodily activities.
Hormones
You only need catabolic hormones. You need catabolic and anabolic hormones.
Effect on the body
Burns all fat and calories in the body It allows the growth, development, maintenance, structure, reproduction and response of the organism to the external environment.
Energy conversions
Potential energy is converted to kinetic energy It is an interconversion between kinetic and potential energy.
Processes
It occurs during cellular respiration, digestion, and excretion. It occurs during photosynthesis synthesis, protein synthesis, glycogen synthesis, digestion, respiration, and excretion.

What is catabolism?

Catabolism is the type of biochemical process in which large molecules and substances become smaller molecules with the release of the amount of energy. Catabolism considers the destructive process with the release of a small amount of heat and energy. He considered the exergonic process. In this process, the end products are produced as waste products such as lactic acid, urea, and carbon dioxide.

Hormones such as glucagon, cortisol, and adrenaline are used in this process. The main importance of this process is that catabolism involves the breakdown and destruction of body fat and calories. It causes the conversion of fats, starches, carbohydrates, proteins and lipids converted into fatty acids, glycerol, monosaccharides, amino acids and Acetyl-CoA. Catabolism occurs primarily during cellular respiration, digestion, and other processes. This process usually occurs in the presence of oxygen which refers to an aerobic process.

The biochemical catabolism reaction generally refers to the energy source and electron source that is perhaps used later in the electron transport chain in the mitochondria. This process is more common in heterotrophs where they obtain their food source by breaking down large molecules and complex substances.

What is metabolism?

Metabolism is the complete package of biochemical reactions in which both types of anabolic and catabolic reactions can occur. Metabolism includes the breakdown of large molecules into smaller subunits and the binding of smaller subunits into larger complex molecules. This process includes the release of energy and the absorption of energy during reactions. The metabolism considers the process destructive and constructive with or without release of heat and energy. Consider the exergonic or endergonic process.

The metabolism needs both catabolic and anabolic hormones in its actions. First, in catabolism, it causes the breakdown of proteins, carbohydrates, and fats into amino acids, monosaccharides, and fatty acids with the release of energy. Then, in anabolism, it causes the binding of amino acids in proteins and fatty acids in lipids with the absorption of energy.

The importance of metabolism is the development of the structure, maintenance, reproduction and development of the human body. It also involves the destruction of fat and calories. The rate at which the metabolism process occurs depends on the amount of food the body eats. This process also occurs rapidly in the presence of enzymes and different hormones.

Key differences

  1. Catabolism is a destructive process, while metabolism is both constructive and destructive.
  2. Catabolism is the aerobic process; on the other hand, metabolism is both an aerobic and an anaerobic process.
  3. Catabolism is the energy release mechanism; on the other hand, metabolism is a process of energy release and absorption.
  4. Catabolism is the process by which potential energy is transformed into kinetic energy. On the other side of the coin, metabolism is the process of interconversion of kinetic energy and potential energy.
  5. Catabolism occurs during bodily activities; on the other hand, metabolism occurs during rest and bodily activities.
  6. Catabolism destroys fat and calories; on the opposite side, metabolism causes structural development.
  7. Catabolism only needs catabolic hormones; on the other hand, the metabolism needs catabolic and anabolic hormones.
  8. Examples of catabolism are respiration and digestion. On the other hand, examples of metabolism are photosynthesis, protein synthesis, and glycogen synthesis.
Final Thought

The above discussion concludes that catabolism is the process of releasing energy, while metabolism is the process of releasing or absorbing energy.
