It is the Flow of energy, where R is the energy used in Respiration by the organisms, whose magnitude with Gross production equals to Net production.
Answer:
The correct answer is E. Lactate and NAD+
Explanation:
Fermentation occurs in anaerobic condition and in humans, most of the energy is provided by aerobic respiration but when the body needs a lot of energy in a very quick time like in sprinting then muscles use lactic acid fermentation to gain energy.
After the consumption of all stored ATP during intense work, our body starts lactic acid fermentation to gain ATP. In lactic acid fermentation, the pyruvate molecule that was produced during glycolysis is converted into lactate molecule. In this process, NADH is oxidized to NAD+.
Therefore in lactic acid fermentation lactate and NAD+ are produced. So the correct answer is E.
Answer:
<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone
<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis
Explanation:
Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.
You would call an 'essay' a serious or witty composition meant to briefly express ideas, views, feelings, or reactions to situations in life. This will make the correct answer C.
