Practice question
Question
An electron micrograph of a bacterium reveals extensions of the plasma membrane in the form of vesicles, tubules and lamellae. Damage to these structures is followed by disturbances in cell-wall formation, DNA distribution, respiration and secretion.
Which structure has most probably been damaged?
Explanation
Mesosomes are extensions of the bacterial plasma membrane that occur as vesicles, tubules and lamellae. They are associated with cell-wall formation, DNA replication and distribution, respiration, secretion, and increased membrane surface area and enzymatic content.
