Question

Aquaporins are proteins embedded in the plasma membrane that allow water molecules to move between the extracellular matrix and the intracellular space. Based on its function and location, describe the key features of the protein’s shape and the chemical characteristics of its amino acids.

a) Aquaporins are hydrophobic with acidic amino acids
b) Aquaporins are hydrophilic with basic amino acids
c) Aquaporins are helical with hydrophobic amino acids
d) Aquaporins are polar with hydrophilic amino acids

Answer 1

Aquaporins are polar integral transmembrane proteins with a hydrophilic channel that allows water molecules to move between the extracellular matrix and the intracellular space.

Step-by-step explanation:

Aquaporins are integral transmembrane proteins that allow for the efficient movement of water molecules between the extracellular matrix and the intracellular space.

They have a hydrophilic channel through their core that provides a hydrated opening for water to pass through the membrane. Aquaporins are polar with hydrophilic amino acids, which allow them to interact with and transport water molecules.
