How does the structure of the plasma membrane determines the route taken by vitamin C and vitamin D?

Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion.
Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.

What determines the flow of the plasma membrane?
God.
What is the bacterial structure that acts as a selective barrier allowing nutrients to enter the cell and wastes to leave the cell.?
plasma membrane
What structure is involved in phagocytosis?
Plasma Membrane !
What are the specialized parts of the phospholipid bilayer and how do their structure's relate to the structure of the plasma membrane?
that meand there no plasma membrene
Which structure regulates passage of molecules into and out of cells?
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
This structure is the outermost boundary of the cell and is semipermeable?
Plasma membrane or cell membrane
What determines the specific functions of the plasma membrane?
The relative amounts of proteins and lipids
Can you clearly see the membrane as a structure?
Yes, the cell membrane can be seen clearly as a structure. The cell membrane is called the plasma membrane and is a barrier between the cell and its environment.
What does the fluid mosaic model?
The fluid mosaic model represents the structure of the plasma membrane. It shows that the plasma membrane consists of a phospholipid bilayer ( with hydrophilic heads- which face the interior and exterior of the plasma membrane- and hydrophobic tails) as well as transport proteins namely carrier proteins and pore proteins. The size and polarity of a molecule determines how it will pass through the semi-permeable plasma membrane whether by simple diffusion, osmosis, facilitated diffusion or active transport.
What is the structure of a plasma membrane and what is the role of their hydrophilic heads?
That is the structure of plasma membrane adjectent or near the secondary cell wall in a cells. It's a living outermost boundary of all the cells.
Which cell structure is represented by the three- dimensional?
Cytoskeleton is 3d structure.It is spreaded through out the cell.
What are the specialized parts of the phospholipid bilayer and how do their structures relate to the structure of the plasma membrane?
that meand there no plasma membrene
