What is metabolism in biology class 11?

“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.

What is metabolism in biology?

Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. … Specific proteins in the body control the chemical reactions of metabolism. Thousands of metabolic reactions happen at the same time — all regulated by the body — to keep our cells healthy and working.

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 do you mean by metabolize?

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.

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).

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. The rate of energy expenditure is usually lowest in the early morning.

What is an example of a metabolic disease?

Some affect the breakdown of amino acids, carbohydrates, or lipids. Another group, mitochondrial diseases, affects the parts of the cells that produce the energy. You can develop a metabolic disorder when some organs, such as your liver or pancreas, become diseased or do not function normally. Diabetes is an example.

Where does metabolism of drugs occur?

Most drugs must pass through the liver, which is the primary site for drug metabolism. Once in the liver, enzymes convert prodrugs to active metabolites or convert active drugs to inactive forms. The liver’s primary mechanism for metabolizing drugs is via a specific group of cytochrome P-450 enzymes.

What controls your metabolism?

Thyroid Essentials: How the Thyroid Gland Works

The thyroid’s main role in the endocrine system is to regulate your metabolism, which is your body’s ability to break down food and convert it to energy. Food essentially fuels the body, and each of our bodies uses that fuel at different rates.

What is anabolism example?

Anabolism is for the synthesis of complex molecules essential in building up of organs and tissues. It is therefore responsible for the increase in body size. Examples of anabolism are bone growth and mineralization, and muscle mass build-up.
