Verified step by step guidance

Understand the definition of an integral membrane protein: Integral membrane proteins are proteins that are permanently embedded within the lipid bilayer of a cell membrane. They interact extensively with the hydrophobic core of the bilayer.

Analyze the options provided: The correct answer must align with the characteristic of being embedded within the lipid bilayer, as this is a defining feature of integral membrane proteins.

Eliminate incorrect options: 'Completely soluble in the cytosol' is incorrect because integral membrane proteins are not soluble; they are embedded in the hydrophobic environment of the membrane. 'Loosely attached to the membrane surface' is incorrect because this describes peripheral membrane proteins, not integral ones. 'Covalently attached to a carbohydrate group' is incorrect because this describes glycoproteins, which may or may not be integral membrane proteins.

Focus on the correct option: 'Embedded within the lipid bilayer' is the correct answer because it directly describes the structural characteristic of integral membrane proteins.

Conclude: Integral membrane proteins are embedded within the lipid bilayer, allowing them to interact with both the hydrophobic core of the membrane and the aqueous environments on either side of the membrane.
