E) all of the above

Question

Quizplus · Accepted Answer

Soluble-gas neurotransmitters are synthesized in the neural cytoplasm (A), immediately diffuse through the cell membrane into the extracellular fluid and into nearby cells upon synthesis (B), can diffuse into target cells through their cell membranes (C), and once in other cells, they stimulate the synthesis of a second messenger and are immediately broken down (D). Therefore, all of the statements (A, B, C, D) are correct, making E the correct choice.
