Answer & Explanation:
Feedback is a form of regulation where the main product of one reaction, can also inhibit it. It can work in several ways, mainly there's a receptor that, somehow, measures the presence of a determined molecule, in this case, ATP. These receptors can also be involved in the metabolic process and when there's an excess of ATP, the enzymes are inhibited, maybe with an allosteric type of inhibition.
<h2>Ovulation </h2>
Explanation:
In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle
- In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
- Around day 14 of the cycle, a surge in luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
- For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
- Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs
