Question

All of the following are true statements except:

a. there are at least 16 different prostaglandins.
b. the first prostaglandin was identified in semen.
c. aspirin produces some of its effects by increasing PGE synthesis.
d. PGFs have been used to induce labor and accelerate the delivery of a baby.

Answer 1

Prostaglandins are a class of compounds with more than 20 different types. The first prostaglandin was discovered in semen. Aspirin inhibits the synthesis of prostaglandins, including PGE, and PGF derivatives are used to induce labor.

Step-by-step explanation:

Based on the given information, we can determine which statements about prostaglandins are true or false:

1. a. There are at least 16 different prostaglandins. This statement is true. Prostaglandins are a large class of compounds, and there are actually more than 20 different types of prostaglandins identified.
2. b. The first prostaglandin was identified in semen. This statement is true. Prostaglandins were initially discovered in seminal fluid from the prostate gland.
3. c. Aspirin produces some of its effects by increasing PGE synthesis. This statement is false. Aspirin actually inhibits the synthesis of prostaglandins, including PGE.
4. d. PGFs have been used to induce labor and accelerate the delivery of a baby. This statement is true. PGF derivatives have been used to induce labor by stimulating uterine contractions.
