Outer most layer
What role does the cytoskeleton play in relation to the cell membrane?
Acts as a base of attachment for the cytoskeleton
What is the composition of the cell membrane?
Composed of two layers of phospholipids and embedded with proteins
What does it mean for the cell membrane to be semi-permeable?
Allows only selected molecules to diffuse across the membrane
What is the role of the cell membrane in protecting the interior of the cell?
Regulates what enters and exits the cell
What is the primary function of the cell membrane?
To regulate the entry and exit of substances
Which statement best describes the composition of the cell membrane?
Composed of two layers of phospholipids and embedded with proteins
What role does the cytoskeleton play in relation to the cell membrane?
It provides a base of attachment for the cell membrane in some organisms
What does it mean for the cell membrane to be semi-permeable?
It permits only selected molecules to diffuse across the membrane
Where is the cell membrane located in an animal cell?
In the outermost layer
What is the role of the cell membrane in protecting the interior of the cell?
To allow only selected substances into the cell and keep unwanted substances out
How does the cell membrane support the cell's structural integrity?
By providing a stable barrier between two aqueous compartments
What are some components responsible for giving membranes their flexibility?
Proteins and lipids
What is the primary function of the proteins embedded in the cell membrane?
To regulate the entry and exit of the cell
Which characteristic best describes the structure of the cell membrane?
Double layer of phospholipids with numerous embedded proteins
What would happen if the cell membrane lost its semi-permeable nature?
The cell would not be able to regulate water balance
What role does the stable barrier formed by the cell membrane play in cellular processes?
It facilitates selective transport and compartmentalization of cellular components
Which statement best explains the diverse functions of the proteins in the cell membrane?
The proteins act as channels, receptors, and enzymes, contributing to various cellular processes
Explore the structure and function of the cell membrane in both prokaryotic and eukaryotic cells. Learn about its composition, location in animal and plant cells, and its role as a semi-permeable barrier regulating the entry of substances.
