How do homeostasis and metabolism differ

Enzymes cannot work unless the body is kept at a consistent temperature. Homeostasis must be maintained within the cells for the reactions required by metabolism to take place. Should the temperature be too high, then the enzymes will stop working; should it be too low, then the rate of reaction increases, which may be just as detrimental.

Optimal metabolic efficiency is maintained by the negative feedback loop by which homeostasis operates. Frederich, M. The relationship between AMP-activated protein kinase activity and AMP concentration in the isolated perfused rat heart.

What is Metabolism 4. Similarities Between Homeostasis and Metabolism 5. Generally, all living organisms must maintain constant internal body conditions regardless of the changing environmental conditions. Homeostasis is this ability of an organism to adjust itself to restrain the external changes and maintain the dynamic constant state of functioning within the body.

Therefore, homeostasis is essential for life. It maintains most regulatory mechanisms of many advanced organisms vertebrates such as heart rate, breathing rate, blood glucose levels, fluid levels, and body temperatures, etc. The advantage of homeostasis is that it allows organisms to survive and function efficiently and effectively in a broad range of environmental conditions. In many organisms, the nervous system controls the homeostasis via nerve impulses. Maintenance of homeostasis involves negative feedback loops that work towards set points of the body.

For example, when the body temperature goes up, the negative feedback loop brings the body temperature towards the setpoint 37 0 C, which is the normal body temperature. However, something that interferes negative feedback loops can disrupt homeostasis. One such condition is diabetes that occurs due to the inability of the pancreas to produce insulin hormone. Metabolism is the set of all chemical reactions that occur in an organism. In simple words, it refers to the set of life-sustaining chemical reactions in an organism.
