adenosine triphosphate (ATP).
Organisms carry out a variety of chemical reactions such as photosynthesis (conversion of light energy into chemical energy), cellular respiration (conversion of glucose into ATP for energy), and protein synthesis (formation of proteins from amino acids). Other reactions include digestion (breakdown of food into nutrients), fermentation (anaerobic breakdown of sugars), and various metabolic pathways (biosynthesis and breakdown of molecules).
These are not chemical reactions but thermonuclear reactions.
The overall term for the collection of chemical reactions that occur in a cell is metabolism. This encompasses all the biochemical processes involved in maintaining life, including energy production, synthesis of molecules, and breakdown of nutrients to release energy. Metabolism consists of two main categories: catabolism (breakdown of molecules to release energy) and anabolism (synthesis of molecules using energy).
During the process of breaking down food to get energy, chemical reactions such as catabolic reactions occur. These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. Key catabolic reactions include glycolysis, the citric acid cycle, and oxidative phosphorylation.

Chemical energy
During the process of breaking down food to get energy, chemical reactions such as catabolic reactions occur. These reactions involve the breakdown of complex molecules into simpler ones, releasing energy in the process. Key catabolic reactions include glycolysis, the citric acid cycle, and oxidative phosphorylation.
Chemical breakdown processes in cells are mainly carried out by enzymes, which catalyze reactions that break down molecules into smaller components. For example, glycolysis breaks down glucose into pyruvate, while the citric acid cycle further breaks down pyruvate into CO2 and ATP. These breakdown processes release energy stored in chemical bonds, which the cell can then use for various cellular activities.
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
The sum of all chemical reactions in a cell is known as metabolism. Metabolism consists of catabolic reactions (breakdown of molecules to release energy) and anabolic reactions (building of molecules using energy). Together, these reactions enable cells to grow, reproduce, maintain their structures, and respond to their environments.
Chemical synthesis involves combining molecules to form new, more complex structures, while breakdown reactions involve breaking down molecules into simpler components. In synthesis reactions, energy is usually required, while in breakdown reactions, energy is typically released. Overall, synthesis reactions build larger molecules, whereas breakdown reactions break down larger molecules into smaller ones.
