Metabolism refers to all of the chemical reactions that take place within an organism by which complex molecules are broken down to produce energy and by which energy is used to build up complex molecules. An example of a metabolic reaction is the one that takes place when a person eats a spoonful of sugar.
What are some examples of metabolic activities?
Metabolism is a balancing act involving two kinds of activities that go on at the same time:
- building up body tissues and energy stores (called anabolism)
- breaking down body tissues and energy stores to get more fuel for body functions (called catabolism)
What are the 5 metabolic processes?
- A summary of metabolism. The unity of life. Biological energy exchanges. …
- The fragmentation of complex molecules. The catabolism of glucose. Glycolysis. …
- The combustion of food materials. The oxidation of molecular fragments. …
- The biosynthesis of cell components. The nature of biosynthesis. …
- Regulation of metabolism. Fine control.
Is digestion an example of metabolism?
Examples include the digestion of a protein into amino acids that the body can absorb from the diet and use in its own metabolism, and the breakdown of stored glycogen in the liver to supply energy between meals. These breakdown processes are known chemically as oxidation reactions.
What are the 4 parts of metabolism?

Is breathing a metabolic activity?
When the respiratory system is mentioned, people generally think of breathing, but breathing is only one of the activities of the respiratory system. The body cells need a continuous supply of oxygen for the metabolic processes that are necessary to maintain life.
What’s metabolic activity?
Metabolic activity is the part of metabolism which takes place in the body of an organism. Metabolism is the phenomenon which includes set of chemical reactions which are essential for a living organism to maintain its life. These are also known as metabolic processes.
What are the 3 metabolic types?
There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don’t use in your normal, day-to-day conversations. But learning the types of body you were born with will help your fitness plan in the long run.
What are the three main metabolic pathways?
There are three metabolic pathways that provide our muscles with energy: the phosphagen pathway, the glycolytic pathway, and the oxidative pathway.
What organs are involved in metabolism?
Your metabolism is reflected in your major organ systems, and here are the five major players that affect how you store, burn and lose weight:
- Your liver. If you were a car, your liver would be like the engine. …
- Your adrenals. …
- Your thyroid. …
- Your pituitary. …
- Your substance.
What is metabolism mean?
What is metabolism? Metabolism describes all the chemical processes that go on continuously inside your body to keep you alive and your organs functioning normally, such as breathing, repairing cells and digesting food. These chemical processes 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 the normal metabolism?
An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day.
What is the importance of metabolism?
The three main purposes of metabolism are: the conversion of food to energy to run cellular processes; the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes.
How does metabolism occur?
Catabolism is the breakdown of organic matter, and anabolism uses energy to construct components of cells, such as proteins and nucleic acids. The chemical reactions in the metabolic process are organized into metabolic pathways whereby one chemical is transformed through a series of steps into another chemical.
How does metabolism affect weight?
Several factors determine your basal metabolic rate: Body size and composition. If you weigh more or have more muscle mass, you’ll burn more calories, even at rest. So people who weigh more are more likely to have a faster basal metabolic rate — not a slower one — because a portion of excess weight is muscle tissue.
