What is Metabolic Reaction? The Science Behind It


What is Metabolic Reaction? The Science Behind It


Metabolism is one of the most vital functions that our body undergoes. It is something that every single person on this planet needs because it sustains our primary life force.

Metabolic reactions occur in our body every moment, whether sitting or sleeping. Therefore, it is essential to understand everything that goes on in one’s body to identify if there is a problem efficiently.

Metabolism is the total chemical reactions involved in maintaining the living conditions of any living organism’s cells. All living organisms require energy to keep their cells functioning.

Metabolic processes help with growth and reproduction, help maintain the structures of living organisms, and enable organisms to respond to their environments. All chemical reactions within living organisms—from digestion to transportation within cells—require energy.

In this regard, metabolic reactions are the biochemical reactions that transform food into energy in our body and its cells. To reiterate, our bodies require this energy to be able to do anything, such as think, grow, or move.

Our bodies contain particular proteins that control chemical reactions. These reactions don’t necessarily happen in isolation, though. Instead, thousands of metabolic reactions occur simultaneously to maintain our cells’ healthy and working properties. The body regulates all of these reactions.

After we eat, our digestive system uses enzymes to break down proteins into amino acids, fats into fatty acids, and carbs into simple sugars like glucose. Then, when our bodies need energy, they use sugars, amino acids, and fatty acids. Finally, these compounds get absorbed into our bloodstream and carried straight to the cells.

When they enter their respective cells, other enzymes regulate the chemical reactions necessary to metabolise these compounds. During these processes, energy from the compounds is released for the body’s use or stored in body tissue, such as the liver, muscles and body fat.

It is important to note that metabolic reactions are integral yet delicate. It takes a significant balancing act, one that involves two reactions happening at the same time.


Anabolism is also known as constructive metabolism because it is all about building and storing things. It helps the growth of new cells, the maintenance of body tissues and storing of energy for future use.

In this reaction, small molecules are changed into more extensive and complex molecules of carbs, fat and protein.


Catabolism, also known as destructive metabolism, is a process that produces the energy necessary for all kinds of activity in the cells.

For example, it helps cells break down larger molecules, such as fats and carbs, to allow the release of energy. It, in turn, actually produces fuel for anabolism, which heats the body and then allows the body’s muscles to contract and move.

The HealthifyMe Note

In conclusion, there are two types of metabolic reactions that take place in our bodies: anabolic reactions and catabolic reactions. Anabolic reactions use energy to build complex molecules from simpler ones, while catabolic reactions break complex molecules down into simpler molecules that release chemical energy.

The regulation of metabolism is a process that manages metabolic pathways in humans. All living organisms need a continuous generation of energy to maintain their processes and functions. In other words, we need it to survive.

So, how do we increase metabolism, then? You can regulate them with the help of the following:

  • Maintaining a healthy body: To be fit and well, one must limit calorie intake and lose extra weight. Individuals eat to provide their bodies with energy to perform all functions. However, eating too much or too little can render one’s body unfit, slowing down the metabolic reactions that provide the body with energy.
  • Combat fatigue: Consume a protein-rich breakfast to boost the body’s metabolism. It will keep one energised throughout the whole day. Individuals who skip their morning meals tend to have poor metabolic energy.
  • Caffeine stimulates the central nervous system, and therefore, it can also activate one’s metabolism rate by up to 8%.
  • Fibre should be an essential part of your diet. Fibre helps to burn fat by at least 30%. Further, people who add more fibre to their daily routine and diet remain well.


Metabolic reactions are everything that the process of metabolism does for your body. Metabolism is a vital and integral process that sustains everything we do and perform.

It provides us with the energy to even think! Therefore, we must do everything we can to ensure that our bodies perform this process correctly. However, if you suspect serious health issues affecting your metabolism, please consult a medical professional before taking action.
