Which statement is true about Braun's lipoprotein? A) It is covalently linked to peptidoglycan in the outer membrane B) It is the most abundant protein in the inner membrane C) It is found only in Gram-positive bacteria D) It repels toxins and antibiotics
Understand the Problem
The question is asking us to identify the accurate statement regarding Braun's lipoprotein and its characteristics in bacterial membranes.
Answer
Braun's lipoprotein is covalently linked to peptidoglycan in the outer membrane.
The final answer is that Braun's lipoprotein is covalently linked to peptidoglycan in the outer membrane.
Answer for screen readers
The final answer is that Braun's lipoprotein is covalently linked to peptidoglycan in the outer membrane.
More Information
Braun's lipoprotein, found in Gram-negative bacteria, is one of the most abundant membrane proteins. It functions by linking the outer membrane to the peptidoglycan layer, helping maintain the structural integrity of the bacterial cell wall.
Tips
A common mistake is confusing the location and function of Braun's lipoprotein; it is not found in Gram-positive bacteria and isn't primarily involved in repelling toxins and antibiotics.
