Energies Life-sustaining

All foods for humans must provide some life-sustaining elements. These elements are the nutrients that supply energy after being metabolized in the body and those that are essential for the body to carry on this metabolism. Other qualifications for a food are its psychological and social effects. Many foods are eaten as a habit, custom, or tradition but all foods must possess acceptable physical attributes, i.e., color and texture, and desirable taste and palatability. 

Biochemistry deals with the structure and function of cells and cellular components such as biopolymers, membranes, and ribosomes. The functions or physical and chemical processes involved in extracting energy from the environment and using that energy for sustaining life are known collectively as metabolism. Metabolism consists of the interaction of two major processes called catabolism and anabolism. 

All processes in the detrital trophic chain run with the participation of microorganisms if they are energy advantageous for them, and are called biochemical processes. They do not conflict with thermodynamic requirements, and microorganisms participating in these processes exist and multiply only under certain conditions optimum for their life-sustaining activity. Such conditions are determined by temperatme, pressure, salinity, acidity, water composition and source of energy.
