diffusion. it is lipophilic and is able to pass through the PM. thyroxine is not water soluble and is the reason why it requires a carrier protein (albumin) for circulation.

Steroid hormones cannot pass through the plasma membranes of their target cells?
false-can
What membranes allow some materials to pass while constraining the movement of other molecules.?
Semi permeable membranes as the plasma membranes in cells of our body.
Does a permeable membrane will let substances pass through it?
Yes it does permeable membranes are membranes that allows all substances to pass through.
What allows water molecules to pass through?
water can pass through cell membranes by osmosis- similar to diffusion
Proteins do not pass through cell membranes because?
g
Thyroxine molecules are too large to pass through the plasma membranes of their target cells?
false- small

The dialysis membranes used in the treatment of kidney disease do not allow plasma protein molecules to pass?
The dialysis membranes used in the treatment of kidney disease do not allow plasma proteins to pass the dialyzing fluid. During kidney dialysis, the constituents of the patients blood pass through the dialysis membrane with the exception of plasma proteins.

What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
What are membranes that allow only certain substances to pass through them?
Semi permeable membranes.
What allows water to pass through?
water can pass through cell membranes by osmosis- similar to diffusion
Does sugar diffuse through the cell membrane?
No. Only non-polar, small molecules can pass through a membrane by simple diffusion. A sucrose molecule is too large a molecule to pass through a membrane by simple diffusion, however, it can pass through a plasma membrane (but not any artificial membranes like Visking tubings) by facilitated diffusion, i.e. through transport proteins(specific carriers for sucrose) embedded in the membranes. ! =)
How can polar molecules pass through cell membranes?
Through facilitated diffusion
