Question

Which of the following is not a way in which antihistamines may affect transduction pathways? (1 point) They prevent enzymes from transforming histidine into histamine. They prevent release of histamine by blocking signal transduction. They reduce cellular response by blocking signal transduction. They reduce histamine in the blood by binding to and destroying it.

Answer 1

The correct answer is : They reduce histamine in the blood by binding to and destroying it.

Step-by-step explanation:

Antihistamines are type of drugs that inhibits release of histamine by binding to histamine receptors and suppress the transduction pathways of histamine.

They blocks the enzymes from transforming histidine into histamine and reduce cell response by blocking histamine-induced cascade signal transduction. These are use to treat allergies, congestion, hay fever and other allergy responses.

Thus, the correct answer is : They reduce histamine in the blood by binding to and destroying it.
