Metabolism refers to the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy. This energy gets used for vital processes and the synthesis of new organic material.
What is metabolism easy definition?
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing.
What is physiological metabolism?

What is metabolism and its types?
“Metabolism refers to a series of chemical reactions that occur in a living organism to sustain life.” Metabolism is the total amount of the biochemical reactions involved in maintaining the living condition of the cells in an organism. … The organisms respond to the surrounding environment due to metabolic activities.
What is metabolism with example?
Metabolic reactions may be categorized as catabolic – the breaking down of compounds (for example, the breaking down of glucose to pyruvate by cellular respiration); or anabolic – the building up (synthesis) of compounds (such as proteins, carbohydrates, lipids, and nucleic acids).
What is metabolism in your own words?
Your metabolism is the result of all the processes in your body working together to create the energy that keeps you going. Your metabolism is the rate at which your body’s many processes function, and it can be low, high, or somewhere in the middle. … Exercising speeds up your metabolism.
What is physiological energy?
Abstract. The physiological energy expenditure involved in common activities such as running, walking, or cycling can be influenced by a variety of biomechanical factors.
Where does metabolism occur in the body?
The liver is the primary site for metabolism. Liver contains the necessary enzymes for metabolism of drugs and other xenobiotics.
What are the steps in carbohydrate metabolism?
The enzyme reactions that form the metabolic pathways for monosaccharide carbohydrates (Chapter 2) include glycolysis, the citric acid cycle, and oxidative phosphorylation as the main means to produce the energy molecule adenosine triphosphate (ATP).
Which fruit is good for metabolism?
Watermelon, cantaloupe, honeydew—these are naturally good for metabolism. Watermelon may even help with weight loss because it contains the amino acid arginine, which was found in a study of obese mice to reduce body fat gains by 64 percent.
