Noun. 1. metabolic process – the organic processes (in a cell or organism) that are necessary for life. metabolism. organism, being – a living thing that has (or can develop) the ability to act or function independently.
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. …

What are metabolic processes give one example?
Anabolic and catabolic pathways
The processes of making and breaking down glucose molecules are both examples of metabolic pathways. A metabolic pathway is a series of connected chemical reactions that feed one another.
What are metabolic processes Class 9?
Catabolism – This process is mainly involved in breaking down larger organic molecules into smaller molecules. This metabolic process releases energy. Anabolism – This process is mainly involved in building up or synthesizing compounds from simpler substances required by the cells.
What are the 3 stages of metabolism?
Terms in this set (7)
- Stage one. Nutrients are digested into absorbable units, into the blood and moved to tissue cells.
- Stage two anabolism. nutrients are made into macromolecules.
- Stage two catabolism. Catabolism: nutrients broken down into pyruvic acid and acetol CoA. …
- Stage three. CO2 released. …
- Proteins. …
- Carbohydrates. …
What are the metabolic processes of the body?
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 two types of metabolic reactions?
Metabolic reactions can be catabolic (directed toward the breakdown of larger molecules to produce energy), or anabolic (directed toward the energy‐consuming synthesis of cellular components from smaller molecules).
What are the basic metabolic pathways?
In humans, the most important metabolic pathways are: glycolysis – glucose oxidation in order to obtain ATP. citric acid cycle (Krebs’ cycle) – acetyl-CoA oxidation in order to obtain GTP and valuable intermediates. oxidative phosphorylation – disposal of the electrons released by glycolysis and citric acid cycle.
Why energy is required in metabolic process?
Cells break down complex carbohydrates into simple sugars that the cell can use for energy. … Just as energy is required to both build and demolish a building, energy is required for both the synthesis and breakdown of molecules. Many cellular process require a steady supply of energy provided by the cell’s metabolism.
What are the four metabolic pathways?
Let us now review the roles of the major pathways of metabolism and the principal sites for their control:
- Glycolysis. …
- Citric acid cycle and oxidative phosphorylation. …
- Pentose phosphate pathway. …
- Gluconeogenesis. …
- Glycogen synthesis and degradation.
What is metabolism and its importance?
Metabolism is the biochemical process of combining nutrients with oxygen to release the energy your our bodies need to function. Your resting metabolic rate (RMR) is the number of calories your body burns to maintain vital body functions such as heart rate, brain function and breathing.
What is metabolism and its type?
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. Anabolism – the synthesis of all compounds needed by the …
What is metabolism in botany?
Plant metabolism is defined as the complex of physical and chemical events of photosynthesis, respiration, and the synthesis and degradation of organic compounds. … This primary metabolism consists of chemical reactions that allow the plant to live.
What are the three main purpose of metabolism?
The three main purposes of metabolism are the conversion of food/fuel 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 nitrogenous wastes.
Where is metabolism located?
Is metabolism cellular level?
Cellular metabolism is the set of chemical reactions that occur in living organisms in order to maintain life. Cellular metabolism involves complex sequences of controlled biochemical reactions, better known as metabolic pathways.
