Question

Secretions from which one of the following are rich in fructose, calcium and some enzymes ?

• A. Male accessory glands
• B. Pancreas
• C. Liver
• D. Salivary glands

Answer 1

The Correct Option is A

To determine the correct answer, let's analyze the composition and function of the secretions produced by each of the given options:

1. Male Accessory Glands:
   • The male accessory glands include the seminal vesicles, prostate gland, and bulbourethral glands.
   • The seminal vesicles produce a yellowish viscous fluid that is rich in fructose, prostaglandins, and clotting proteins. Fructose serves as an energy source for sperm.
   • The prostate gland secretes a slightly alkaline fluid that contains enzymes, calcium, and other components that enhance sperm mobility and viability.
   • The presence of fructose, calcium, and enzymes aligns with the composition mentioned in the question.
2. Pancreas:
   • The pancreas produces pancreatic juice which contains digestive enzymes (e.g., amylase, lipase) and bicarbonate to aid in digestion.
   • It does not specifically produce secretions rich in fructose and calcium for reproductive purposes.
3. Liver:
   • The liver secretes bile, which is rich in bile salts, bilirubin, and cholesterol. It helps in the digestion of fats and is stored in the gallbladder.
   • The liver's secretions do not match the composition described in the question.
4. Salivary Glands:
   • The primary secretion of salivary glands is saliva, which contains enzymes like amylase, mucins, and electrolytes.
   • Saliva does not contain fructose and calcium in significant amounts for reproductive purposes.

After evaluating each option, we conclude that the male accessory glands are indeed responsible for secretions rich in fructose, calcium, and enzymes, which support the function and viability of sperm cells. Therefore, the correct answer is Male accessory glands.
