What is the fundamental role of the cell membrane in maintaining homeostasis?
What is the fundamental role of the cell membrane in maintaining homeostasis?
The cell membrane acts as a gatekeeper, controlling the passage of substances into and out of the cell, thus regulating the cell's internal environment and maintaining homeostasis.
Explain how the process of shivering contributes to maintaining homeostasis in the human body.
Explain how the process of shivering contributes to maintaining homeostasis in the human body.
Shivering generates heat by rapid muscle contractions, which helps to raise the body temperature back to its set point, maintaining a stable internal environment.
How do some antibiotics disrupt bacterial homeostasis, ultimately leading to their death?
How do some antibiotics disrupt bacterial homeostasis, ultimately leading to their death?
Certain antibiotics disrupt bacterial homeostasis by damaging their cell membranes, creating holes that allow essential molecules to leak out and disrupt the delicate balance of the internal environment.

Study Notes
Homeostasis
- Homeostasis is the ability of a system to maintain a stable internal environment.
- It is derived from two Greek words: "homeo" meaning "constant" and "stasis" meaning "stable".
- It is crucial for cells to maintain homeostasis in order to function properly.
- An example of homeostasis is your body maintaining temperature.
- When it's cold, your body shivers, generating heat to maintain a stable body temperature.
- When it's hot, you sweat, which helps cool your body down.
The Cell Membrane: the Gateway to Homeostasis
- The cell membrane is a vital structure found in ALL living cells.
- It acts as a gatekeeper, controlling what enters and exits the cell.
- This regulation is crucial for maintaining the cell's internal environment and staying in homeostasis.
- Antibiotics sometimes work by disrupting cell membranes, leading to the death of bacteria.
- By causing tiny holes in the bacterial cell membrane, the antibiotics disrupt homeostasis, ultimately killing the bacteria.
