Most living organisms especially aquatic life function at the optimal pH range of 6.5 to 8.5. pH is important because the enzymes that catalyze the chemical reactions of life require a specific pH in order to function. Why is it important that the bodys internal environment is kept constant? For example, homestasis in the body can mean a temp of 98.6 F. If a body is not in homeostasis, it cannot function properly. 3 What is pH and why is it important for living things to maintain homeostasis of pH? Acids cause tooth decay : When we eat sugary food it gets degraded by bacteria present in the mouth and an acid is formed. each move. How does an organism maintain a constant body temperature? And How is Stopping Distant Effected? When soil pH is extremely high or low the plants growing in it may suffer from nutrient deficiencies or toxicities. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to. The term widely used in chemistry biology and agronomy translates the values of the concentration of the hydrogen ionwhich ordinarily ranges between about 1 and 1014 gram-equivalents per litreinto numbers between 0 and 14. Answer (1 of 25): It is necessary to maintain optimal conditions for metabolism to progress properly. Importance of pH Balance Our bodies live and die at a cellular level and the cells must maintain alkalinity in order to function and stay alive.
