What is the cell membrane gateway system specifically called?
The cell membrane gateway system is specifically called the cell membrane transport system. This system allows for the movement of molecules, ions, and other substances across the cell membrane through various mechanisms such as passive diffusion, facilitated diffusion, and active transport.
What part of the cell protects the cell from invaders?
The cell membrane acts as a barrier that protects the cell from invaders by controlling what enters and exits the cell. Additionally, the immune response triggered by the cell's internal defense mechanisms, like lysosomes and phagocytes, play a key role in protecting the cell from invaders.
What transport mechanisms involves the movement of water in a cell?
The membrane of a cell is semipermeable. Water and small molecules flow freely into and out of the cell. There is no transport mechanism. The fluidity of the membrane designated by the fluid mosaic model, allows for water to flow freely into and out of the cell.
What supervises substances entering and exiting the cell?
The cell membrane supervises the substances entering and exiting the cell. It is selectively permeable and regulates the passage of molecules in and out of the cell through active or passive transport mechanisms.
Where does respiration happen in eukaryotes and in prokaryotes?
In eukaryotes respiration happens in the mitochondria and in prokaryotes the mechanisms of respiration are in the cell membrane as protons must be taken in through the membrane.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
Which part of a cell controls what gets in and out?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.

How does a cell control what enters and leaves?
A cell controls what enters and leaves through its selectively permeable cell membrane. This membrane allows only specific molecules to pass in and out through various mechanisms like active transport, passive transport, and facilitated diffusion. Additionally, the cell may use protein channels or pumps to regulate the movement of substances in and out of the cell.
Molecules can pass through the cell membrane of the human cell?
Yes, molecules can pass through the cell membrane of human cells through various mechanisms such as simple diffusion, facilitated diffusion, or active transport. The size, polarity, and concentration gradient of the molecule influence how it crosses the cell membrane.
What makes up the selectively premeable membrane that controls which molecules enter and leave the cell?
A cell's membrane is made up of a phospholipid bilayer which has several protein channels and various other transport mechanisms built in.
What part of the cell protects the cell from invaders?
The cell membrane acts as a barrier that protects the cell from invaders by controlling what enters and exits the cell. Additionally, the immune response triggered by the cell's internal defense mechanisms, like lysosomes and phagocytes, play a key role in protecting the cell from invaders.
What feature of cell prevents water from entering the cell?
Phospholipids in the cell membrane prevent water from entering a cell.
What transport mechanisms involves the movement of water in a cell?
The membrane of a cell is semipermeable. Water and small molecules flow freely into and out of the cell. There is no transport mechanism. The fluidity of the membrane designated by the fluid mosaic model, allows for water to flow freely into and out of the cell.

What keeps the cytoplasm inside and allows nutrients in and waste products out?
The cell membrane keeps the cytoplasm inside the cell. It is selectively permeable, allowing nutrients to enter and waste products to exit through various transport mechanisms like diffusion, osmosis, and active transport.
What supervises substances entering and exiting the cell?
The cell membrane supervises the substances entering and exiting the cell. It is selectively permeable and regulates the passage of molecules in and out of the cell through active or passive transport mechanisms.
