Metabolism is the set of life-sustaining chemical reactions in organisms that enable them to grow, reproduce, maintain their structures, and respond to environmental changes. It involves two main processes: catabolism, which breaks down molecules to produce energy, and anabolism, which uses energy to construct components of cells such as proteins and nucleic acids.

Metabolism

Chemical reactions involve the transformation of substances through the breaking and forming of chemical bonds, resulting in the conversion of reactants into products. These reactions are governed by the principles of thermodynamics and kinetics, which dictate the feasibility and rate of these transformations.

Environmental changes refer to the alterations in the natural or human-made environment that can affect ecosystems, biodiversity, and human societies. These changes can be driven by natural processes or human activities, leading to impacts such as climate change, habitat loss, and pollution.

Catabolism is the metabolic pathway that breaks down molecules into smaller units, releasing energy that is used to power cellular processes. It is an essential part of metabolism, balancing the energy needs of the cell by converting complex molecules into simpler ones and facilitating the release of energy stored in chemical bonds.

catabolism

The process of breaking down molecules, known as catabolism, is essential for cellular respiration and energy production. This involves enzymatic reactions that convert complex molecules into simpler ones, releasing energy stored in chemical bonds.

Anabolism is the aspect of metabolism that involves the synthesis of complex molecules from simpler ones, crucial for cell growth, repair, and differentiation. It requires energy input, typically in the form of ATP, to drive the biosynthetic processes that build up cellular structures and store energy for future use.

Proteins are complex macromolecules essential for various biological functions, including catalyzing metabolic reactions, DNA replication, and transporting molecules. They are composed of amino acids linked in a specific sequence, which determines their structure and function.

proteins

Nucleic acids, including DNA and RNA, are essential biomolecules that store and transmit genetic information in all living organisms. They are composed of long chains of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base, enabling the encoding of genetic instructions for the development, functioning, and reproduction of life.
