Question

Discuss the possible fonction of plasma membrane of pseudomonas​

Answer 1

Answer:

Distinctive characteristics of the cell membrane in the Pseudomonas genus:

- low outer membrane permeability

- protein channels for the uptake of nutrients

- porin proteins with cell adhesion and signaling functions

Explanation:  

The plasma membrane is a lipid bilayer that separates the cytoplasm of the prokaryotic cell from the external environment. The cell membrane is selectively permeable in order to regulate the transport of substances (nutrients and cell waste products). Pseudomonas is a genus of Gram-negative bacteria that have a thin peptidoglycan layer and an outer membrane. In Pseudomonas species, the cell membrane contains porin proteins involved in the uptake of nutrients, such as, for example, OprB, OprB2 (glucose), OprG (phosphate) and OprH (pyrophosphate). Moreover, the cell membrane of these bacteria has low outer permeability, which confers a high resistance to antibiotics.
