Which of the following is false regarding the bacterial membrane?
- A
Bacteria contain plasma membranes that are made up of triglycerides.
- B
Gram staining reveals that bacteria contain cell walls, but no cell membranes.
- C
Bacteria do not contain a membrane-bound nucleus, but they contain an analogous membrane-bound structure called the nucleoid.
- D
All of these are incorrect.
All the options are false.
This is incorrect because bacteria do not contain plasma membranes made up of triglycerides. Bacterial plasma membranes are mainly composed of phospholipids, which are a type of lipid molecule that contains a glycerol backbone, two fatty acid chains, and a phosphate group.
That statement is incorrect. Gram staining reveals the presence of both cell walls and cell membranes in bacteria.
Bacteria lack the membrane bound nuclei of eukaryotes, their DNA forms a tangle known as nucleoid but there is no membrane around it hence this option is not correct.
This is the correct option as all the options are false regarding bacterial membrane
