metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing 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 does it mean to metabolize in biology?
biology : to change (food) into a form that can be used by your body : to process and use (substances brought into your body) by metabolism. See the full definition for metabolize in the English Language Learners Dictionary. metabolize.
What is metabolism and examples?
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 are the examples of metabolic?
An example of a metabolic reaction is the one that takes place when a person eats a spoonful of sugar. Once inside the body, sugar molecules are broken down into simpler molecules with the release of energy.
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 are the 3 types of metabolism?
These three metabolism types are endomorph, ectomorph, and mesomorph.
What 2 molecules are the most important energy sources in food we eat?
Carbohydrates and lipids are the most important energy sources in foods you eat. However, this energy is only usable after these molecules are broken down by a series of chemical reactions.
What is metabolism in the human body?
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism. Metabolism can be conveniently divided into two categories: Catabolism – the breakdown of molecules to obtain energy.
What is high metabolism?
The faster your metabolism, the more calories your body needs. Metabolism is the reason some people can eat a lot without gaining weight, while others seem to need less to accumulate fat. The speed of your metabolism is commonly known as metabolic rate.
What is metabolism and how it works?
Metabolism is the process by which your body converts what you eat and drink into energy. During this complex process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.
What is the process of metabolism?
Metabolism is the term for a set of chemical reactions that occur in the cells of living organisms to sustain life. The metabolic processes lead to growth and reproduction and allow living organisms to maintain their structures and respond to the surrounding environment.

What do Metabolic mean?
Metabolic: Relating to metabolism, the whole range of biochemical processes that occur within us (or any living organism). … The term “metabolic” is often used to refer specifically to the breakdown of food and its transformation into energy.
What are metabolic by products?
A metabolic product is a compound produced by the cells and is excreted to the extracellular medium. It could be produced in the primary metabolism, e.g. carbon dioxide, ethanol, acetate, or lactate, or a more complex one, e.g. a secondary metabolite or a heterologous protein secreted to the extracellular medium.
