LIFE SCIENCE

Detailed explanation-1: -This phospholipid bilayer determines what molecules can move into or out of the cell, and so is in large part responsible for maintaining the delicate homeostasis of each cell.

Detailed explanation-2: -Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization.

Detailed explanation-3: -The ‘cell membrane’ (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.

Detailed explanation-4: -Answer and Explanation: The structure most responsible for maintaining cell homeostasis is the cell membrane. The cell membrane is a thin, flexible barrier that protects the cell. It also is selectively permeable, meaning it only lets certain things in and out of the cell.
