Question

Quizplus · Accepted Answer

Transmembrane sensor kinase proteins can sense environmental conditions outside Gram-positive bacteria or in the periplasm of Gram-negative bacteria. This is because Gram-negative bacteria have an outer membrane that encloses the periplasm, whereas Gram-positive bacteria do not, allowing direct sensing of the environment.
