Metabolism Definition, 2 Types, Goals, Functions, and Processes

In this article, we will discuss Metabolism Definition, Types, Goals, Functions, Processes, and Differences between metabolism and digestion

Metabolism is a number of chemical reactions that occur in every cell of a living organism. Metabolism adjusts energy for vital processes and forms new energy.

Refer to Encyclopedia Britannica (2015) metabolism is associated with body activity. To determine the function of the body’s organs, improve cells, digestion of food, and breathing.

Metabolism definition

Metabolism comes from the Greek “metabolismos” which means change. As the name suggests, the metabolism is all chemical reactions that occur in the organism belongs to the cell level.

Metabolism is the body’s speed process of digesting, absorbing, and assimilating food to convert into energy.

The faster the metabolism, the faster the calorie burning process. So the healthy ideal weight is maintained.

After knowing Metabolism Definition, next are The metabolism Types, Goals, Functions, Processes, and Differences between metabolism and digestion

Metabolism Types

Broadly, metabolism has a two-way trajectory of organic chemical reactions, namely:

  • Catabolism, is a reaction in which the process of breaking down molecules of organic compounds, such as the breakdown of glucose into a pyruvate by cellular respiration.
  • Anabolism, is a reaction in which process of assembling (synthesis) organic compounds, such as proteins, carbohydrates, lipids, and nucleic acids in certain molecules.

Differences between metabolism and digestion

The process of digesting is actually more interpreted as the process that the body does to process and break down food into nutrients. This process is entirely occurring in the digestive organs, such as the stomach and intestines.

Meanwhile, metabolic processes can occur in various cells in the body controlled by special proteins. This energy formation process has even begun since the first time you formed in the womb, and will stop when you die.

Simply put, metabolism is preceded by the digestive process.

Metabolism main goals

Metabolism has three purposes, namely:

  1. Convert food into energy to conduct cellular processes;
  2. Convert food / fuel into protein constituents, lipids, nucleic acids and some carbohydrates;
  3. Disposal of nitrogen waste. The reactions catalogued by this enzyme allow the organism to grow and multiply, maintain its structure, and respond to its environment.

Metabolism function

Metabolism is one of the characteristics of living things. In humans, metabolism will digest food to be processed into energy. In addition to aiming to form energy, metabolism has the following functions:

1# Replacing Damaged Cells

In the process of protein metabolism, there will be the evolution of two compounds, namely polymers and monomer amino acids. Polymer itself is a protein that has various functions such as compiling cell structure and altering damaged cells, to the point that the metabolic processes of proteins, the destruction of cells or tissues in the body can be addressed quickly.

2# Tissue Respiration in the Body

This function can be obtained when the body’s metabolic processes are in good and maximum situations, as well as the nutrient intake required by the body is well fulfilled.

3# Body Tissue Growth

Need to know, almost all nutrients that enter the body of living beings have the same benefits that are for the development of body tissues. So when nutrients can be processed into energy, then the development of tissues will also occur automatically.

4# Compiler Cell Building Units

Not only is it beneficial to change damaged cells, but metabolism is also beneficial for assembling cell building units, especially protein metabolism.

5# Produce energy

Produce energy, from changes in food substances that exist in the body

The body’s metabolic processes

There are several metabolic factors in the body, as follows:

Basal metabolism

Metabolism definition - process

Metabolism is related to the number of calories burned in the body. This energy, as a power capital to pass on daily activities.

This metabolism occurs when the body is able to keep important organs functioning properly.

For example, the body is able to convert food into energy that can be used for activities.

This metabolism accounts for 70 percent of the body’s overall metabolic processes.

NEAT (Non exercise activity thermogenesis)

Non-exercise activity thermogenesis, in which this metabolism is related to all calories burned when feeling worried or shivering.

Thermogenesis is the production of heat that occurs after eating, which plays a role in increasing the metabolic rate of the body, which will increase energy expenditure.

This metabolism accounts for 20 percent of the body’s metabolism.

Human activity

Metabolism is influenced by human activity. In daily work as well as regular exercise.
