Question

Seminal plasma in humans is rich in:
a. Fructose, calcium and certain enzymes.
b. Fructose, calcium and certain enzymes.
c. Fructose, calcium and but has no enzymes.
d. Glucose and certain enzymes but have no calcium.

Answer 1

Hint:
Semen is a male reproductive fluid that consists of sperms and seminal plasma.
Semen, also called seminal fluid, fluid that is emitted from the male reproductive tract and that contains sperm cells, which are capable of fertilizing the female's eggs.
Amino acids, citrate, enzymes, flavins, fructose the main energy source of sperm cells, which rely entirely on sugars from the seminal plasma for energy), phosphorylcholine, prostaglandins, proteins, vitamin C.
The major components of the seminal plasma in the male reproductive system are mucus, spermatozoa, and various secretions of accessory glands.

Complete answer:
a. FRUCTOSE, AND CERTAIN ENZYMES BUT POOR CALCIUM:- semen does contain actual nutrients including vitamin C, B12, ascorbic acid, calcium, citric acid, fructose, lactic acid, magnesium, zinc, potassium, sodium, fat and protein. So this option is not correct.
b. FRUCTOSE, CALCIUM AND CERTAIN ENZYMES :- The seminal plasma is rich in fructose, calcium, ascorbic acid, and certain enzymes. It provides nourishment and protection to sperms. So, this option is correct.
c. FRUCTOSE, CALCIUM BUT HAS NO ENZYMES :- Seminal plasma is a highly complex biological fluid containing proteins, amino acids, enzymes, fructose and other carbohydrates, lipids, major minerals and trace elements. So, this option is also wrong as seminal plasma contains enzyme
d. GLUCOSE AND CERTAIN ENZYMES BUT NO CALCIUM:- seminal plasma contains calcium so this option is incorrect.
So, the correct answer is option b) that is fructose calcium and certain enzymes.

Note: Seminal plasma is the fluid portion of semen, secreted by both the epididymis as well as the accessory glands before and during ejaculation. Seminal plasma is a complex fluid, which serves as a vehicle for transporting ejaculated spermatozoa towards their journey from the testes to their target, the oocyte.
Spermatozoa are produced in the testes and transported to the epididymis along with the seminiferous tubular fluid. The spermatozoa leaving the epididymis along with the epididymal fluid will join the secretions from the prostate and seminal vesicles, thus forming the seminal plasma.
