Answer:
The answer to fill in the blank in this question: Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of:____, would be: cAMP.
Explanation:
In the process of hormonal regulation of cells there are two ways in which this can happen: direct activation of DNA inside a cell through steroid hormones, who do not need any kind of mediators to enter the cytoplasm of a cell and activate its genetic material, or indirect activation, which is the common way for non-steroidal hormones, such as epinephrine. In this second scenario a hormone will reach the cell and lock onto a receptor on the plasma membrane. The effect is that a G-protein, which is adjacent to the receptor, activates the second-messenger system, meaning that the activity the hormone came to initiate, will depend on these mediators. the G-protein will then activate adenylate cyclase, which in turn will activate ATP and transform it into cAMP. It is cyclic AMP (cAMP) which will finally relay the original message sent through the hormone, to the genetic material of the cell.
Low calorie food intake can lead to amenorrhea (loss of regular menstrual cycle) and protein deficiency.
What is amenorrhea and protein deficiency and its effects?
- Female athletes, find it difficult to meet energy and nutrient needs while maintaining a low fat or body weight considered optimal for sports performance. Thus, they often restrict energy intake(EI) to make weight goals.
- Low EI, combined with high levels of exercise, increases the risk of developing exercise-related menstrual dysfunction (ExMD) and poor bone health.
- ExMD can be high in physically active women, ranging from 0% to 60%, and occurs across a continuum from mild disruptions in menses (no ovulation or luteal phase deficiency) to oligomenorrhea (cycles ≥ 35 day) and amenorrhea (no menses for >90 day.
- Low energy availability (EA) (i.e., energy remaining for body functions after exercise training) may lead to menstrual dysfunction through a leptin-controlled pathway.
- In ExMD, females have low leptin levels that contribute to the disruption of luteinizing hormone (LH) pulsatility via interference of gonadotropin-releasing hormone (GnRH) pulsatile.
- Sequentially, the ovaries decrease production of estrogen and progesterone, the hormones responsible for triggering the lining and egg of the uterus to be shed (menstruation) resulting in abnormal menses.
- Adequate dietary protein is important for supporting physiological adaptations to exercise, there is a growing need to determine the protein requirements for pre-menopausal
- athletes that address the influence of endogenous and exogenous hormones and potential metabolic
