Question

Where are integral proteins present in the membrane?

Answer 1

Integral Proteins:

1. The plasma membrane is a bilipid layer, so these integral proteins contain residues with hydrophobic side chains that penetrates the fatty acyl regions of the phospholipid layer, thus anchoring the protein to the membrane.
2. They carry out functions such as channeling or transporting molecules across the membrane .
3. Other integral proteins act as cell receptors.

Location:

1. An integral membrane protein is a type of membrane protein (IMP), that is permanently embedded within the plasma membrane.
2. In the membrane, the integral proteins are fully or partially buried.
