Question

Porins:

• A. Are cytoskeletal proteins
• B. Form channels which allow passage of hydrophilic molecules
• C. Are fatty acids
• D. Are pores in the stem of a plant

Hint:

Remember that porins form channels to allow the passage of hydrophilic molecules in bacterial membranes.

Answer 1

The Correct Option is B

Porins are membrane proteins that form channels allowing the passage of small hydrophilic molecules, such as ions or small nutrients, across the bacterial outer membrane. They are not cytoskeletal proteins or fatty acids, and they are not related to plant pores.
