Knowing these terms will not only help keep your weight in check but maintain overall health. For the unversed, metabolism is the process in which our body breaks down the food we eat and convert it into energy required by it to perform daily functions. It is a crucial part of the overall growth and functionality of all living things. Metabolism includes two other processes, including catabolism and anabolism. Catabolism and anabolism are the broad classes of the biochemical reactions that together make up metabolism.
While catabolism breaks down molecules, anabolism is the growth and building of complex molecules. So, the main difference between the two terms is that metabolism describes all chemical reactions involved in maintaining the living state of our cells. Catabolism, on the other hand, is a type of metabolism that is responsible for breaking complex molecules into smaller molecules.
What is metabolism? Metabolism is the rate at which our body burns calories to keep you healthy. From maintaining a healthy weight to keeping diseases at bay, metabolism helps in everything. A sedentary lifestyle can slow down your metabolism and take a toll on your health.
It is important to maintain overall health by keeping your metabolism in check. According to Healthline, it involves two processes - anabolism and catabolism that help organize molecules by freeing and capturing energy to keep the body strong. What is catabolism?
As mentioned above, catabolism is the process in which your body breaks down the complex molecules into smaller and simpler ones to use for energy. The hormones associated with catabolism include adrenaline, cortisol, cytokines and glucagon.
Catabolic reactions are considered to produce ATP energy required by the anabolic reactions. During catabolism, waste products like urea, ammonia, lactic acid, acetic acid and carbon dioxide are also produced. Many hormones such as adrenaline, cortisol, and glucagon are also involved in this process. During digestion , complex macromolecules like starch, fats, and proteins from the diet are taken up and broken down into small units like monosaccharides, fatty acids, and amino acids , respectively by digestive enzymes.
These monosaccharides are then used in the glycolysis to produce acetyl-CoA. Catabolism of proteins , polysaccharides, and fats are shown in figure 1. Figure 1: An overview of protein, polysaccharides and fats catabolism. Fatty acids are used to produce acetyl-CoA by beta oxidation.
Amino acids are either reused in the synthesis of proteins or oxidized into urea in the urea cycle. Depending on the utilization of organic compounds either as the carbon source or electron donor, organisms are classified as heterotrophs and organotrophs, respectively. Monosaccharides like intermediately complex organic molecules are broken down by heterotrophs in order to generate the energy required for the cellular processes. Organic molecules are broken down by organotrophs in order to produce electrons, which can be used in their electron transport chain, generating ATP energy.
The whole set of biochemical reactions occurring in the body is collectively referred to as metabolism. Three major phases are found in metabolism. First, during catabolism, carbohydrates , proteins, fats and nucleic acids in food are broken down into their small monomer units and nitrogenous wastes are eliminated.
Secondly, the resultant monomers like glucose are used as substrates in the cellular respiration by generating energy. Thirdly, during anabolism, small monomer units are polymerized into complex molecules like polypeptides, lipids polysaccharides, and nucleic acids. Metabolism takes place through metabolic pathways. This means, one chemical compound is converted into its end product of the pathway through a series of biochemical reactions.
Each biochemical reaction is catalyzed by unique enzymes. Through the presence of enzymes to catalyze each reaction, these reactions can be regulated in such a way to achieve the required energy by the organism. On the other hand, these enzyme-catalyzed reactions, which require energy are coupled with spontaneous reactions, which release the energy.
The rate of the metabolism depends on the amount of food taken by the organism. Your body needs high-quality building blocks to heal, repair and grow. Different types of exercise are considered anabolic or catabolic, depending on whether they use energy to build or break down something.
Cardiovascular workouts catabolic are great for burning a lot of calories quickly. Anabolism and catabolism are both crucial parts of your metabolism. They fuel your everyday activities, from jogging to healing a paper cut.
The best way to support those processes and boost your metabolism is to adopt healthy habits. Anabolism and catabolism are key parts of your overall metabolism.
