In Biological Membranes,the Phospholipids are Arranged in a _______,With the _______

Question

In biological membranes,the phospholipids are arranged in a _______,with the _______.
A) bilayer;fatty acids pointing toward each other
B) bilayer;fatty acids facing outward
C) single layer;fatty acids facing the interior of the cell
D) single layer;phosphorus-containing region facing the interior of the cell
E) bilayer;phosphorus groups in the interior of the membrane

Accepted Answer

Biological membranes are composed of a bilayer of phospholipids, with the hydrophobic fatty acid tails facing each other and the hydrophilic phosphorus-containing head groups facing outward on both sides of the membrane. This arrangement creates a barrier between the cell and its environment, while also allowing certain molecules to pass through the membrane.
