Any molecule smaller than the holes in the membrane can pass through is the membrane is permeable. If the membrane is semi-permeable, then only molecules that the membrane selects can pass through. Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.

What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Which type of molecule is found in the plasma membrane?
The plasma membrane is composed mostly of phospholipids
What is the Plasma membrane lipid that improves the rigidity of the plasma membrane and increases the membrane's impermeability to water?
Type your answer here... cholesterol
What molecules passively diffuse across the plasma membrane?
Diffusion is a type of passive transport but the answer I think you are looking for is this: water, gasses(N,O2,CO2...), and ions(K+, Na+...)
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
On the outer surface of the plasma membrane there are marker molecules that identify the cell-type Often these molecules are?
These molecules are typically membrane carbohydrates. These assist in the identification of the type of cell.
What type of Phospholipids that make up the plasma membrane?
the one in plasma membrane
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
What type of membrane is membrane plasma?
The plasma membrane is referred to as a biological membrane or bio-membrane.Briefly, the plasma membrane may also be generally referred to as cell membrane.

Ions cannot cross back and forth across the neuron cell membrane?
Water diffuses across the plasma membrane, and this can affect cell size and .... proceeds, the different type cells of the embryo develop their ... or ion so that it can cross the plasma .... molecules cannot cross the membrane because they are un- able to ... plasma membrane and the back and forth arrows indicate that these.
Which of the following incorrectly matches the type of cell type of protein and site of the proteins synthesis?
prokaryote, plasma membrane protein, ribosome bound to plasma membrane
What type of plasma membrane transport is used for exchange?
Diffusion
What molecules passively diffuse across the plasma membrane?
Diffusion is a type of passive transport but the answer I think you are looking for is this: water, gasses(N,O2,CO2...), and ions(K+, Na+...)
Why can molecules that are fat-soluble permeate across a cell membrane?
Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.
