Question

Homeostasis is

• A. the phenomenon by which the same group of metabolites that can make the reaction static
• B. the state of steady internal chemical and physical conditions maintained by living systems
• C. a process by which metabolic pathways are stopped
• D. a process that explains the structure and mechanism of enzyme action

Answer 1

The correct option is B the state of steady internal chemical and physical conditions maintained by living systems

Homeostasis is the state of steady internal chemical and physical conditions maintained by living systems. The maintenance of a constant internal environment is necessary as any deviation may cause denaturation of proteins and enzymes. Almost all the biochemical metabolic cycles are controlled by enzymes and hormones. Various feedback mechanisms exist within the organism to maintain proper synthesis of hormones, enzymes and other metabolites. An increase or decrease in their optimum concentration can cause disorders in the organism and may even be fatal. Homeostasis can occur to maintain optimum body temperature, water levels, glucose concentration in the blood, etc.
