Question

The _____________ are a pair of glands that produce a thick, yellowish, fructose-rich fluid that makes up about 60% of the seminal fluid.

Answer 1

The seminal vesicles are a pair of glands that produce a significant portion of the seminal fluid, which is alkaline and contains nutrients and enzymes beneficial for sperm motility and survival.

Step-by-step explanation:

The seminal vesicles are a pair of glands responsible for producing a thick, yellowish, fructose-rich fluid that comprises about 60% of the seminal fluid. Seminal vesicle fluid is alkaline, which is crucial as sperm are only motile in an alkaline environment, and helps to counteract the acidity of the vaginal environment. This fluid also contains mucus, fructose as a nutrient for sperm mitochondria, a coagulating enzyme, ascorbic acid, and local-acting hormones known as prostaglandins.
