Proteins are biological polymers constructed from amino acids joined together to form peptides. These peptide subunits may bond with other peptides to form more complex structures. Multiple types of chemical bonds hold proteins together and bind them to other molecules. Take a closer look at the chemical bonds responsible for protein structure.

Answer:
The correct answer is option b. gonadotropin-releasing hormone.
Explanation:
The GnRH or the gonadotropin-releasing hormone is a releasing hormone that releases from the neurons of the hypothalamus. This releasing hormone is responsible for the secretion of the luteinizing hormone and follicle-stimulating hormone.
GnRH regulates both gonadotropin hormones, in which, LH (luteinizing hormone) responsible for the regulation of the male reproductive system and FSH (follicle-stimulating hormone) responsible for the female reproductive system and sperm production in testes in males.
Thus, the correct answer is option B. gonadotropin-releasing hormone.
