Trillions of cells build the human body, and their lifespan processes keep organs and systems alive. The most significant operations are metabolism to grow and reproduction of cells, as they support an organism’s overall environment. Fermentation, aerobic and anaerobic respiration are essential parts of this maintenance. Microbes apply them for nutrition to get enough energy to grow and function. Cellular energy is represented as adenosine triphosphate (ATP), which cannot be produced without fermentation and respiration.

The ability of cells to grow and the quality of their reproduction depends on the way metabolism works with the consumed substances. Cells get nutrients to turn on the metabolic process with chemicals used to build blocks and store or use energy (Bauman, 2018). Further catabolism of the nutrients is crucial for metabolism to proceed in cells. Fermentation helps break nutrients into energy, while respiration forces the reaction of glucose and oxygen to form ATP for cells. Biner et al. (2020) state that “the ability to provide a constant supply of ATP is crucial for the construction of cells” (p.1450). Energy is stored in ATP bonds, therefore aerobic and anaerobic respiration should proceed with enough ATP. Fermentation breaks chemicals into energy and enzymes to catabolize nutrient molecules for constructing precursor metabolites. Enzymes are also necessary to move anabolic reactions between energy from ATP with metabolites.
The metabolic algorithm turns nutrients and chemicals into the building material to develop cells that grow by assembling cell walls and insights like ribosomes. The process cannot happen without fermentation and ATP managed by aerobic and anaerobic respiration. Each step’s performance is important for the overall survival of microbes because any deviation severely affects metabolism, slows cell recreation, therefore damages the full functionality of a body. The reproduction of cells in the process of dividing themselves into two parts, which usually appears when a microbe doubles its original size. Cellular metabolism has to operate appropriately to give a cell enough energy, therefore fermentation, aerobic and anaerobic respiration are vital for the microbes to reproduce.
