Metabolism consists of two different processes:
Metabolism is the process of breaking nutrients into fundamental components and then building it up in several useful ways. It can be useful for structure, useful for providing energy so that it is easier for us to sustain our lives with all processes such as reproduction, growth and response to surroundings.
Metabolism Definition- It can be defined as all the chemical reactions taking place inside of a cell often linked in pathways or chains. In some of the chemical reactions taking place during metabolism, energy is released and in others, energy is added for the reactions to take place. A metabolism example of the former case is cellular respiration where a sugar molecule is broken down and energy is released in the form of ATP (Adenosine Triphosphate); an example of the latter is photosynthesis where sunlight energy is used by plants to convert carbon dioxide into sugar molecules.
Metabolism consists of two different processes:
A metabolic pathway is a series of linked chemical reactions that include making and breaking down glucose molecules and releasing or utilising energy. The building up pathway is Anabolic pathway whereas breaking down pathways is a catabolic pathway. Let’s discuss these two pathways in detail:
It helps in building complex molecules from simpler molecules and here energy is consumed i.e. it needs the input of energy. A few examples of the anabolic pathway include-
It involves the breakdown of complex molecules into simpler ones and is a pathway that releases energy in the form of ATP. Metabolism examples for the catabolic pathway include-
When we eat food, the molecules are converted to amino acids, sugars and fatty acids with the release of ATP (energy) and waste materials like Nitrogen, CO2, Phosphorus and Sulphur excreted out of the body. Here, we can see whatever we put inside our body in the form of food, it changed into another form. The outcomes of the catabolic pathway are absorbed by our intestines, enter the bloodstream and then are distributed to the body cells. Its functions include- The energized cell forms replacement parts for its own molecules which are worn out and other times, it builds energy molecules in the body. These act like fuel to power the cell’s future activities. Example- Muscle cells use energy molecules to contract and brain cells utilize them to form thought processes.
A protein acting as a catalyst that facilitates reactions in biological systems are called enzymes. Each reaction step in Metabolic pathways is catalyzed by an enzyme and it takes control of the biochemical reactions.
It is an organic compound that provides energy for facilitating many processes in living cells, for example, muscle contraction, chemical synthesis and nerve impulse propagation. It is found in all forms of life, and is often referred to as the “molecular unit of currency”. When consumed in metabolic processes, it is either converted to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP). [Image will be uploaded soon]
The metabolism in human body process depends on the nutrients we intake which are then digested to produce energy. The energy generated by the processes is further utilized to synthesize nucleic acids, proteins and other biomolecules. Having enough nutrients in the body to sustain life is essential in the continuation of metabolic activities regularly. Having low nutrient food results in poor health; the best nutrients for maintaining the right amount of nutrition, thus facilitating metabolic activities and producing energy are Carbohydrates, Fats and Proteins.
Metabolism is the set of biochemical reactions in organisms that are required to sustain life. The major three functions of metabolism include
The catabolic pathway and the anabolic pathways are the two pathways that take place in metabolism. The catabolic pathway is meant to break complex substances into a simpler form with the release of energy in the form of ATP and the anabolic pathway is meant to build larger molecules from smaller molecules and they consume energy for this process.
ATP stands for Adenosine triphosphate. It is an organic compound and it provides energy to drive many processes in a living cell. It is often referred to as the molecular unit of currency that captures chemical energy received from the breakdown of food molecules and then releases it to give power to the other cellular processes. It is very important for all the metabolic reactions taking place in the body. In biochemistry terms, ATP is a nucleoside triphosphate, indicating that it consists of three components: a nitrogenous base (adenine), the sugar (ribose) and the triphosphate.
There is a great importance of metabolism in the human body. High metabolism is good if you want to burn more calories and get in shape as it helps you burn calories even at rest including during activities. Maintaining body weight is easier for people having higher metabolic rates and people sometimes struggle to lose weight as metabolism is hindered in their body due to various factors such as losing muscle mass and gaining more body fat. Therefore, one can increase metabolism if they eat a balanced diet containing lots of protein making it 20-30 percent of their food intake. Also, high intensity workouts, getting a calm night’s sleep and using various spices in diet like turmeric, cinnamon, fennel seeds, cardamom, rosemary, cumin and ginger will help increase metabolism in the human body.
Most of the junk foods are associated with slowing down the metabolism as these contain unhealthy fats. White flour, soda and soft drinks with high fructose quantity, beef, etc. are used in such foods which are not considered good for a healthy body.
