Question

Quizplus · Accepted Answer

The question is asking for the type of opioids and their specific names. "Exogenous" refers to opioids that come from outside the body, while "endogenous" refers to opioids that are naturally produced within the body. The question is asking for the latter, so we can eliminate choices A and C. Between "tau" and "met," only "met" is a valid ending for the specific names of enkephalins. Therefore, the correct answer is D: endogenous; met.
