Cellular respiration is a collection of metabolic events and activities that take place in the cells of animals in order to transform chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then to discharge waste products into the surrounding environment. The reactions that take place during respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy as weak high-energy links, such as those found in molecular oxygen, are replaced by stronger bonds in the products of the reaction. One of the most important ways a cell releases chemical energy to power cellular activity is through respiration.
Aerobic Respiration
Aerobic Respiration is a type of breathing that occurs in the absence of oxygen.
Aerobic respiration is the term used to describe the series of processes catalysed by enzymes. Furthermore, this mechanism includes the transfer of electrons from molecules that serve as a source of fuel, such as glucose, to molecules that serve as a source of oxygen. It also serves as the final electron acceptor, which is an important role.
As a result, it is the primary channel via which energy is produced in aerobic respiration. After all is said and done, this system provides ATP and metabolic intermediates, which are used as precursors for various other pathways in the cell, including carbohydrates, lipid and protein synthesis and other metabolic processes.
The equation for aerobic respiration is:
