Question

In a phospholipid bilayer, the ___________ of the phospholipid molecules are oriented in an inward position.

Answer 1

In a phospholipid bilayer, the tails of the phospholipid molecules are oriented in an inward position.

Step-by-step explanation:

In a phospholipid bilayer, the tails of the phospholipid molecules are oriented in an inward position. The polar heads of the phospholipids face outward, towards the watery environment on both sides of the membrane. This arrangement allows the hydrophobic tails to avoid contact with water and form a stable bilayer structure.
