Answer: Glucose
Explanation:
The carbon based molecule which is broken by the cells of the body is glucose it is a carbohydrate that is obtained from food we consume it is stored in the form of glycogen. When the energy requirement of the body increases then glucose monomers are released from the glycogen chain so that glucose monomers can participate in the energy generation process in the mitochondria of the cell. The chemical energy so produced is ATP (adenosine triphosphate).
The switch from mitosis to meiosis in spermatogenesis is regulated by Follicle-stimulating hormone (FSH) levels of Luteinizing hormone (LH) and this is induced by Glial cell line-derived neurotrophic factor (GDNF).
<h3>How does FSH, LH and GDNF help in spermatogenesis?</h3>
- The development and maintenance of spermatogenesis is dependent on the pituitary gonadotropins; FSH and LH.
- FSH works on Sertoli cells and LH on Leydig cells through their receptors FSHR and LHR respectively.
- Self-renewal and differentiation of the spermatogonial stem cells (SSCs) is regulated by soluble factors produced by the somatic Sertoli cells. One of these is glial cell line–derived neurotrophic factor (GDNF).
