Gonadotropin-releasing hormone is one of the releasing hormones secreted by the hypothalamus to regulate the secretion of hormones from the anterior pituitary gland.
At the beginning of puberty, the hypothalamus begins to increase its production of gonadotropin-releasing hormone (GnRH). The gonadotropin-releasing hormone makes the anterior pituitary to release gonadotropins in both males and females. Two gonadotropic hormones are FSH (follicle-stimulating hormone) and LH (luteinizing hormone). FSH promotes spermatogenesis in the seminiferous tubules, and LH promotes androgen production in the interstitial cells.
Photosynthesis requires sunlight, carbon dioxide and water to produce glucose. This simple sugar is a carbohydrate that combines with other sugars to form the plant's structure and stores energy for future use. Hope it's useful!
It is a cycle because oxaloacetic acid (oxaloacetate) is the exact molecule needed to accept an acetyl-CoA molecule and start another turn of the cycle
