an integral membrane protein would have to be ________________________ to be placed inside the bilayer plasma membrane.
○ electric
○ composed primarily of alpha helix structural domains.
○ hydrophilic
○ amphipathic, with at least one hydrophobic and one hydrophilic region.

Explanation:

The plasma membrane is a phospholipid bilayer, with hydrophobic tails forming the inner core and hydrophilic heads facing the aqueous environments inside and outside the cell. Integral membrane proteins embed within this bilayer, so they need regions that interact with both the hydrophobic inner layer and the hydrophilic surfaces. Electric properties, alpha helix composition alone, or only hydrophilicity do not enable proper embedding in the bilayer structure.

Answer:

O amphipathic, with at least one hydrophobic and one hydrophilic region.
