Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The structure most responsible for maintaining cell homeostasis is the ____
A
cytoplasm
B
cell wall
C
mitochondrion
D
plasma membrane or cell membrane
Explanation: 

Detailed explanation-1: -The main organelle responsible for maintaining homeostasis is the cell membrane. Why is the cell membrane so important for maintaining homeostasis? The cell membrane, also known as the plasma membrane, plays an important role in homeostasis via the regulation of the passage of materials into and out of the cell.

Detailed explanation-2: -One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

Detailed explanation-3: -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.
