What is the meaning of metabolism?
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 the best definition of metabolism?
Metabolism: The whole range of biochemical processes that occur within a living organism. Metabolism consists of anabolism (the buildup of substances) and catabolism (the breakdown of substances). The term metabolism is commonly used to refer specifically to the breakdown of food and its transformation into energy.
What is metabolism short answer?
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 meant by metabolism and give examples?
Metabolism is the total amount of the biochemical reactions involved in maintaining the living condition of the cells in an organism. … All the chemical reactions occurring in the living organisms from digestion to transportation of substances from cell to cell require energy.
What does high metabolism mean?
If your metabolism is “high” (or fast), you will burn more calories at rest and during activity. A high metabolism means you’ll need to take in more calories to maintain your weight. That’s one reason why some people can eat more than others without gaining weight.
What is an example of metabolism?
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. … Catabolism is the process by which large molecules are broken down into smaller ones with the release of energy.
Why is the metabolism important?
Metabolism refers to all the chemical processes going on continuously inside your body that allow life and normal functioning (maintaining normal functioning in the body is called homeostasis). These processes include those that break down nutrients from our food, and those that build and repair our body.
What is metabolism in layman terms?
Metabolism is the chemical reactions which keep us alive. … Reactions catalyzed by enzymes allow organisms to grow, reproduce, maintain their structures, and respond to their environments. The word ‘metabolism’ can also refer to digestion and the transport of substances into and between different cells.
What is metabolism PDF?
Metabolism is defined as the chemical processes by which cells produce the substances and energy needed to sustain life. It is subdivided into: Anabolism – the phase of metabolism in which complex molecules, such as the proteins and fats that make up body tissue, are formed from simpler ones.

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 are the two types of metabolism?
There are two categories of metabolism: catabolism and anabolism. Catabolism is the breakdown of organic matter, and anabolism uses energy to construct components of cells, such as proteins and nucleic acids.
What is metabolism mention the role of enzymes is metabolism?
Some enzymes help to break down large nutrient molecules, such as proteins, fats, and carbohydrates, into smaller molecules. This process occurs during the digestion of foodstuffs in the stomach and intestines of animals.
