Question

Location and secretion of Leydig’s cells are

• A. Ovary – ­estrogen
• B. Liver – ­cholesterol
• C. Pancreas­ – glucagon
• D. Testis – ­testosterone

Answer 1

The correct option is D

Testis – ­testosterone

The correct option is D

Explanation of the correct option:

1. The main source of testosterone or androgens in males is the Leydig cell.
2. This physiology enables them to exert a significant influence over a variety of important physiological processes in males, including spermatogenesis, the regulation of sexual development, and the maintenance of secondary sexual traits and behaviors.

Explanation of the incorrect option:

Option A:

1. The ovaries are the main organs that manufacture estrogens.
2. After the egg has been released from the follicle and from the placenta, they are released by the follicles on the ovaries and are also produced by the corpus luteum.

Option B:

1. Very low-density lipoprotein (VLDL) particles are also responsible for carrying triglycerides into tissues.
2. But the liver is what produces them. VLDLs are converted to intermediate-density lipoproteins and, with additional fatty acid extraction, to LDL particles by the body's cells.

Option C:

1. A hormone called glucagon is important in regulating blood sugar (glucose) levels.
2. It is created by alpha cells in the pancreatic islets of Langerhans, where it is then released into the bloodstream.

Final answer: Location and secretion of Leydig’s cells are Testis – ­testosterone.
