Question
Explain the mechanisms via which a pH level outside of homeostatic range negatively affects body function. can you please be specific?
It is important to maintain optimal pH in the extracellular fluid otherwise illness and death can occur. Explain the mechanisms via which a pH level outside of homeostatic range negatively affects body function.

Step1 a) The maintenance, or regulation, of vital internal variables in a condition of relative consistency is referred to as homeostasis. Homeostasis is influenced by automatic cellular systems, neurological and endocrine regulation, and behaviour. Organisms that function in a larger variety of external conditions have more sophisticated systems regulating crucial variables, such as the flexible processes that allow mammals to function in a far greater range of external temperatures than reptiles. The majority of physiological homeostatic systems rely on negative feedback, which occurs when signals relating to the regulated variable are detected and the system reacts by reducing the signals. Step2 b) Homeostasis maintains ideal conditions for enzyme functioning and all cell activities throughout the body. It is the preservation of a constant internal environment in the face of changing internal and external circumstances. Controlling blood glucose content is one of them in the human body. Because cells rely on the body's environment to exist and operate, conditions in the body must be constantly monitored. The preservation of circumstances by homeostasis is critical since certain processes (osmosis) and proteins (enzymes) will not work effectively under the wrong body settings. Because the activity of most chemical reactions via enzyme proteins is dependent on fluid pH, one of the most fundamental physiological roles of homeostasis is the regulation of body fluid pH.
