Homeostasis (normal cells) o The normal cell is a highly complex unit in which the various organelles and enzyme systems continuously carry out the metabolic activities that maintain cell viability and support its normal functions. Normal function is dependent on: Dthe immediate environment of the cell; 2a continuous supply of nutrients such as oxygen, glucose,and amino acids; 3constant removal of the products of metabolism, including CO2Homeostasis (normal cells)  The normal cell is a highly complex unit in which the various organelles and enzyme systems continuously carry out the metabolic activities that maintain cell viability and support its normal functions.  Normal function is dependent on: ①the immediate environment of the cell; ②a continuous supply of nutrients such as oxygen, glucose, and amino acids; ③constant removal of the products of metabolism, including CO2
